25053 - a:hover causes font size change and subsequent reflow

Status: VERIFIED WORKSFORME

(Core :: CSS Parsing and Computation, defect, P3)

Description

[Phil "clef" Sweeney]

Build: 2000012520 (and other previous builds)

Load above URL and mouse over on some links.

Notice how the font changes and everything moves around.

Also the right side of the page is not visible until you put the mouse over some 
of the links on the right hand side and then it moves in bit by bit.

Sorry:  Does not occur on IE5.  The actual font is changing also, not just size. 
 (Or maybe size isn't changing and just the font)

I'm seeing a problem on http://slashdot.org that might be related.

Scroll down to the article "PSX2 To Replace Your PC?"  and mouse over the
'rosewood' link.  The entire middle column disappears!

Attachment: Demonstration of disappearing content

The attachment I just created is the slashdot page content that's causing this
(since it will change).  This is on this morning's build (Feb 2) on Linux.

Hm I see this content problem even without putting the mouse over anything.  
Maybe there's regression elsewhere.  (win32 build 2000020108)

Another good candidate for the bug contest: could someone write a testcase?
Thanks.

Note: you can't see the reflow on the Mac although when you mouse over links, the 
machine is as sluggish as if a reflow was occuring.

Ignore the comments and testcase from [e-mail]. The problem with 
disappearing tables on mouseover is filed under bug 26015.

Reassigned back to me these bugs that shouldn't have left my list.

Comment 13

[Marc Attinasi]

I am seeing the same problems reported in bug 7617: namely putting focus on a 
link or a button causes a reflow where sizes of table elements shift. I cannot 
see anything wrong on hover, or a font change happening.

This looks like a dup of bug 7617 to me - is anyone else seeing a font change as 
reported? If not, I recommend marking as a dup.

[Sebastian Späth]

I'd say this is different from bug 7617. This one reflows on a mouseover, while 
7617 reflowes only when actually clicked (not when moving over a mousebutton)

I'm not sure that 29877 is entirely a duplicate, but it is very similar at 
least.  I spent a little time looking at google. I'll attach my minimized test 
case.  I don't see any of the contained object returning back anything unusual 
during incremental reflow. I think the table is not handling the incremetnal 
reflow correctly itself.  The resizing problem is probably somewhat different 
than the disappearing content problem.  All these bugs should probably be 
separated into 3 categories:  
1) disappearing content on hover which chris already checked in a fix for (bug 
29429)
2) unnecessary reflows on content state changes, which I will check in a fix for 
tonight (bug 28553)
3) table resizing on certain incremental reflows when contained objects get 
focus (maybe this bug, and bug 29877)

It doesn't happen anymore, it may have been fixed by buster.
