INode::Get First Element Child() const with selectioncaret .enabled turned on on desktop
This bug was filed from the Socorro interface and is report bp-feba3b8e-65c6-4877-8cdb-150482150225. ============================================================= Steps to reproduce: 1. Enable selectioncaret.enabled on desktop (I tested on Mac), and restart. 2. In an open window, click on the location bar. This is caused by PresShell::GetSelectionCaretsStartElement() returning null, and the caller (SelectionCarets::GetStartFrameRectInner) not testing its return value. Ting-Yu, do you have time to fix this? Should be an easy fix. Thanks!
Ehsan, I can reproduce this locally. Investigating.

UL has no CanvasFrame. Hence no SelectionCarets elements. SelectionCarets should ignore the events if it cannot get its elements.

Comment on attachment 8569593 [details] [diff] [review] Ignore events if there's no SelectionCarets elements. (v1) Looks good. Do we need same check in TouchCaret?

Do we need same check in TouchCaret? TouchCaret is fine. It's protected by IsDisplayable() at the beginning of HandleEvent().  http://hg.mozilla.org/mozilla-central/annotate/9b077c6f3d02/layout/base/TouchCaret.cpp#l594
