Timothy Nikkel ddeb475085 Bug 1687927. Don't request a repaint for a scroll update of type NewScrollFrame that doesn't change the scroll offset. r=botond ... https://searchfox.org/mozilla-central/rev/2c06b16a0c15ae340a0532e319cbf89ef9d21b68/gfx/layers/apz/src/AsyncPanZoomController.cpp#4866 scrollOffsetUpdated gets set to true if we get basically any scroll update, including a NewScrollFrame update that we create for every new scroll frame that just informs apzc the scroll offset is (0,0). scrollOffsetUpdated being true means RequestContentRepaint gets called a little later. RequestContentRepaint causes a full display port to be set on the content. That is undesirable because we set zero margin display ports (via SetZeroMarginDisplayPortOnAsyncScrollableAncestors) and we don't want to expand them to full display ports. This bug is to fix the regression caused by bug 1662013. Two other bugs also regressed this (bug 1627012 and bug 1667475), and we need to fix all of them to fix the problem. Bug 1687886 is filed for the regression from bug 1667475. Bug 1687926 is filed for the regression from bug 1627012. Before https://hg.mozilla.org/integration/autoland/rev/b78646d59e32 we only set scrollOffsetUpdated to true if GetScrollOffsetUpdated() was set to true on the metrics, and it didn't get set to true for new scroll frames.
