[APZ] overflow: auto/scroll; would not scroll on scrollber by mouse wheel when apz enabled
Build Identifier: https://hg.mozilla.org/integration/mozilla-inbound/rev/da38bd42a863a6b3228500912a1bb2766ff79166 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0 ID:20151020024007 Steps To Reproduce: 1. Open attached testcase 2. mouse over scrollbar(not thumb) of Box1 and turn mouse wheel one tick --- may work as expected if no scrollbar on root element 3. mouse over scrollbar(not thumb) of Box2 and turn mouse wheel one tick --- does not work, BUG!!! 4. mouse over scrollbar(not thumb) of Box3 and turn mouse wheel one tick --- does not work, BUG!!! Actual Results: Not scroll the element. However, It may work 2nd tick Expected Results: these elements should scroll properly Bug 1190112 and Bug 1213324 did not fix the problem. It works when disable APZ
Silly bug in the patch for bug 1213324 prevented this test case from being fixed too. We can't use NULL_SCROLL_ID to check whether we're building a scrollbar frame since that's used when the scrollframe isn't active.
