1150225 - Mouse cursor sticks to resizing appearance from sidebar when over web page.

Status: RESOLVED DUPLICATE of bug 1018639

(Toolkit :: General, defect)

Attachment: ReaderView_WrongCursorReadingList.mp4

When moving the cursor over the sidebar and back to Reader View, it previous appearance stay until hoovering text. So the Hand- or Resize-cursor stay even when on buttons in the Reader View toolbar. (see video)

It also happens with the Bookmark toolbar, and a non-Reading-Mode page, as shown in https://dl.dropboxusercontent.com/u/2301433/Firefox/ResizePersistence.mov so I'm going to claim that this is a Toolkit bug, not a Firefox or Reader Mode bug.  :)

mCursor in PuppetWidget is different from mCursor in nsWindow.
nsWindow(main-window or top-level-window?) has mCursor and PuppetWidget(browser-pane) has its own mCursor too.(it is bad managed state-holder, imo) PuppetWidget doesn't know changes in nsWindow.

ClearCachedWidgetCursor is called earlier.

This issue seems to be resolved with Bug 1018639 - [e10s] Mouse cursor indicates a bidirectional resize.

I agree, and have verified that it works in the latest nightly in both e10s and non-e10s mode.
Resolving as a dupe.  Thanks!  :)
