340035 - cursor shouldn't change when the microsummary service loads content

Status: RESOLVED WONTFIX

(Firefox Graveyard :: Microsummaries, defect, P5)

Description

[Myk Melez [:myk] [@mykmelez]]

When the microsummary service loads page content via hidden iframes in the browser window, the cursor changes to a busy state for the duration of the load (and then remains stuck on busy because of bug 337038).  It shouldn't change state at all.

Gavin notes nsDocShell::OnStateChange and nsEventStateManager::UpdateCursor, one or both of which might need to be somehow suppressed for microsummary-originated loads in order to fix this problem:

http://lxr.mozilla.org/seamonkey/source/docshell/base/nsDocShell.cpp#4713
http://lxr.mozilla.org/seamonkey/source/content/events/src/nsEventStateManager.cpp#2313

But the fix for bug 339543 will make these loads much faster, perhaps causing noticable changes to the cursor state to become much rarer and thus less of a problem.

Bug 339543 has now been checked in, making these loads much faster.  Also, the fix for bug 342508 now sets the LOAD_BACKGROUND flag on microsummary page loads, which should suppress UI notification of load state, resolving this bug.

But I think I still see busy cursors, if only briefly.  Are others still seeing the same thing?  If so, this'll probably have to wait until Firefox 3, so setting target milestone accordingly.
