Bug 1476345 - Disable the address form save button when the form is invalid. r=jaws Tests for this are in the next commit (e.g. test_address_form.html) because this can't be tested properly due to existing tests not filling fields in ways that fire input/change events.

Bug 1431255 - Part XIII, Make <link> in UA Widget load stylesheets synchronously Set SheetLoadData::mSyncLoad to true when the link element is in a UA Widget. MozReview-Commit-ID: 2NPSJnL0rKl

Bug 1431255 - Part XII, Don't set hidden explicitly on animating elements For elements with an animationProp, always set its hidden state from the startFade() method, so the reverse-direction animation can be correctly cancelled. Additionally, considers elements with "fadeout" class as hidden, so other states can be toggled correctly. This patch fixes intermittent failures on slower platforms, and perma-orange on Windows.

Bug 1431255 - Part XI, Remove bogus comments in videocontrols.js Also removing unremoved <xul:slider> properties and workarounds. MozReview-Commit-ID: 8JrcDyDOBWS

Bug 1431255 - Part X, Remove XBL workaround in bug 462114 This is documented throughly in bug 448909 comment 79. It is no longer needed for our current setup. MozReview-Commit-ID: 9XWCqGUYHW4

Bug 1431255 - Part IX, Remove fullscreenchange workaround for bug 718107 Acknowledge the control bar hidden behavior caused by the bug. Also, set the cursor state before early return, because the video might not be in the same fullsreen state the last time control bar is hidden/shown. MozReview-Commit-ID: 3oN3r8dsUvH

Bug 1431255 - Part VIII, Adjust videocontrols tests to test on UA Widget Duplicates the unchanged tests to xbl dir, ensuring the legacy XBL videocontrols continue to work. Opt out of related reftests until we've found a way to load the UA Widget in reftests. Also opt out of DevTools test until a decision is made on the representation of UA Widgets in the inspector.

Bug 1431255 - Part VII, Trap mouse/touch/pointer events in audio/video element for UI Widgets This is akin to what's done in bug 1327097. MozReview-Commit-ID: EERkjrxWZOu

Bug 1431255 - Part VI, Redirect target in ContextMenu.jsm to HTMLMediaElement Set the referenced node to that of the containing media element so related menu items will be shown in the context menu. MozReview-Commit-ID: 4BKlINHmTSb

Bug 1431255 - Part V, Set the reflectors of the UA Widget DOM to UA Widget Scope The DOM elements within the UA Widget Shadow DOM should have its reflectors in the UA Widget Scope. This is done by calling nsINode::IsInUAWidget() which would check its containing shadow and its UA Widget bit. To prevent JS access of the DOM element before it is in the UA Widget Shadom DOM tree, various DOM methods are set to inaccessible to UA Widget script. It would need to use the two special methods in ShadowRoot instead to insert the DOM directly into the shadow tree. MozReview-Commit-ID: Jz9iCaVIoij

Bug 1431255 - Part IV, Load videocontrols.js, migrated from videoControls binding videocontrols.js handles the controls attribute with a callback named "onattributechange" called by UAWidgets, replaces the CSS selectors. MozReview-Commit-ID: 8rrw0Pbu8Dj

Bug 1431255 - Part III, Create per-origin sandboxes from XPCJSRuntime and load UA widgets scripts This patch creates the basic structure on how the widget scripts can be loaded and be pointed to the Shadow Root, from tab-content.js. This should be moved to another JSM later so we could reuse it on Fennec. The UAWidgets class asks for a sandbox from Cu.getUAWidgetScope(), which calls into XPCJSRuntime::GetUAWidgetScope(). It creates and keeps the sandboxes, in a GCHashMap keyed to the origin, so we could reuse it if needed. MozReview-Commit-ID: J6W4PDQWMcN

Bug 1431255 - Part II, Create a Shadow Root in HTMLMediaElement when enabled, skipping <xul:videocontrols> This prevents XBL binding from being attached, and create the Shadow Root to host controls to be created by the script. Shadow Root and the JS controls are lazily constructed when the controls attribute is set. Set nsVideoFrame as dynamic-leaf so it will ignore content child frames when the controls are XBL anonymous content, and handles child frames from controls in the Shadow DOM. The content nodes are still ignored since there is no <slot>s in our Shadow DOM. MozReview-Commit-ID: 3hk41iMa07n
