Remove additional setting of m
Needs Refreshes = true to ns Transition Manager::Walk Transition Rule
In Bug 1025709, an additional setting of mNeedsRefreshes = true as added to nsTransitionManager::WalkTransitionRule: http://hg.mozilla.org/mozilla-central/rev/31695984cfe2#l5.65 now at: http://hg.mozilla.org/mozilla-central/file/738469449872/layout/style/nsTransitionManager.cpp#l655 According to bug 1048838 comment 19 this may cause unnecessary work when we have multiple style flushes. We should see if there is a way to remove this. Also, while we're at it, as also mentioned in bug 1048838 comment 19, we should also investigate why WalkTransitionRule needs a null-check.
For what it's worth: * I've been running for at least a month (desktop and B2G phone) with the mNeedsRefreshes = true removed, and haven't noticed any problems. * there was a problem when I removed the null-check
I removed the removal from my tree because it was breaking all but the first transition in https://bug1110277.bugzilla.mozilla.org/attachment.cgi?id=8535092 , at least back when I was debugging that testcase.
This works for me, even for the test case in comment 2. Applies on top of the patch for bug 1117603.

I'm waiting for bug 1117603 to land before I land this.
Looks like this might trigger a test failure after all: browser/components/customizableui/test/browser_989751_subviewbutton_class.js | Uncaught exception - Condition timed out: () => !PanelUI.multiView.hasAttribute("transitioning")
After some changes in bug 1117603, looks like this might be ok now but I've retriggered the jobs that failed last time in case I just happened to get lucky: https://treeherder.mozilla.org/#/jobs?repo=try&revision=7c0d57b67523
Backed out because it blocked bug 1117603 from being backed out. https://hg.mozilla.org/integration/mozilla-inbound/rev/5329cda711c8
Can this reland now that bug 1117603 stuck?
(In reply to David Baron [:dbaron] ⏰UTC-7 from comment #11) > Can this reland now that bug 1117603 stuck? Yes! (I was just running it through try over the weekend and making sure bug 1117603 really stuck this time!) https://hg.mozilla.org/integration/mozilla-inbound/rev/7edc16a9d48f Try run: https://treeherder.mozilla.org/#/jobs?repo=try&revision=72968ef6f7ef
