servo: Merge #18664 - stylo: Don't serialize default position on -moz- prefixed linear gradient (from canaltinova:gradient-default-direction); r=emilio Normally, we should not serialize if the line direction points downwards. Unprefixed and -webkit- prefixed syntaxes use only Keyword enum for line direction and we check them already. But -moz- prefixed linear gradients can store position too. Therefore it's stored inside `LineDirection::MozPosition` and we should check that for consistency between other gradients. --- <!-- Thank you for contributing to Servo!

servo: Merge #18666 - style: Avoid creating element data in Servo_ResolvePseudoStyle (from emilio:mathml-is-not-fun); r=bholley The reason the patch in bug 1402285 doesn't work is that we call this function multiple times with the same element.

Bug 1384829 - 4. Add test case to testInputConnection; r=esawin Add a test case to testInputConnection that makes sure GeckoEditable's Editable interface still behaves correctly even after disconnecting from Gecko due to a blur. MozReview-Commit-ID: 7Z6Kpv2tpRy

Bug 1384829 - 3. No longer ignore certain exceptions; r=esawin Bug 817386 added code to ignore IndexOutOfBoundsException when using GeckoEditable because the code wasn't mature enough back then, and there were many race conditions. I think the situation is a lot better now, so we can try removing that code and see if we still need it. We can always add it back if we do. MozReview-Commit-ID: 4pirfaUuSNu

Bug 1403821 - Don't force the allocator to be always compiled with optimizations. r=froydnj This was done in bug 1104634 because back then the Android NDK had a broken combination of compiler and libc, where the compiler would emit calls to the ffs function, but the libc wouldn't contain them, but only when building without optimization. Things have changed in the meanwhile, and recent NDK doesn't have this problem. So we can remove the hack.
