Bug 1706483 - Make openContextMenuSubmenu wait for the submenu to open. r=harry Without this, devtools/client/debugger/test/mochitest/browser_dbg-watchpoints.js was timing out for me locally with non-native menus. Differential Revision: https://phabricator.services.mozilla.com/D112839

Bug 1706483 - Make callers of selectContextMenuItem wait for the context menu to open before calling selectContextMenuItem. r=jdescottes This makes it work with native menus, which open asynchronously. Differential Revision: https://phabricator.services.mozilla.com/D112826

Bug 1688703 - avoid leaks in browser_openTabAndSendCertInfo.js r=johannh openFromPopUp in browser_openTabAndSendCertInfo.js would open a new browser window and then close it quickly without checking its contents. It seems that doing this caused frequent intermittent leaks on ASAN builds. This patch works around the issue by waiting for the window to finish loading and checking that it has the expected contents. This patch also adds the same contents check to other tests in this file that were missing it. Depends on D106340 Differential Revision: https://phabricator.services.mozilla.com/D112639

Bug 1706259 - fix styling in the protocol handler dialogs to be more like the design, r=mconley This starts using the same spacing as commonDialog for these dialogs with proton enabled. It also updates the checkbox spacing, alignment and colour (bug 1705882 will fix the correct colour choice here.) The spacing is still not ideal in the second dialog (after you click 'Choose Application') but there isn't much we can do about that unless we get rid of the confirmation text about where to change the preference, or we start creating ways for the dialog to tell SubDialog to resize it when items are added/removed, which is not straightforward, so I decided not to tackle that here.
