121913 - content sometimes out of order (CSS table display types with anonymous frames)

Status: RESOLVED WORKSFORME

(Core :: CSS Parsing and Computation, defect)

Description

[Brett Denny]

While viewing mozillazine, it appears that stylesheets load after the page
completes and sometimes not at all.  *Usually* after a page reload they appear
again but on initial load many times the text is displayed without any styling
and once the page completes the text is reflowed with the style applied.

Steps to reproduce:
Visit www.mozillazine.org

Expected Results: 
Page displays with styles as it loads

Actual Results:
Styles are applied after page load.

bug 121787 is about CSS backgrounds not loading, not about stylesheets.

What is it that changes after the page loads?

Confirming on Windows build 2002012503.
Making summary more clear.
Haven't seen this until last week or so ==> regression.

dbaron, if you view one of the larger discussions like
http://mozillazine.org/talkback.html?article=2143 most of the time the page gets
layed out as a narrow column on the left side of the viewport with the sidebar
that's supposed to be on the right side of  the page placed underneath the
discussion. I'm guessing that we need to do another reflow or something once we
have the stylesheet data that gives the placement of the columns. 

This seems to happen more as the page gets larger. new discussions with only a
few posts don't have the problem nearly as often as the longer discussions. 

Also, switching the style sheed with View|Use Stylesheet fixes the layout.

Well, I see the problem now, but I don't think it has anything to do with
stylesheets not being loaded.  It's not fixed by a restyle or a reflow, but I
suspect it would be fixed by a full frame reconstruct.

I should debug it a little more before giving it to someone else, though.

Duplicate of bug 121142?

These are different bugs. The bug 121142 is about the content displayed in one
narrow column. But the original report of this bug is about the stylesheet is
being applied only after page load completes.
I don't understand the summary of this bug, maybe it was incorrectly changed.

The original reporter of this bug saw a symptom and assigned a
much-too-technical (and incorrect) diagnosis of the cause, I think.

Sorry, I hadn't followed the bug in awhile... actually, if I remember correctly,
my original summary was completely different than what is there now... something
more to the effect that stylesheets are loaded after the page loads.  I think
the meaning of my explanation was lost somewhere.   What I was seeing what that
while the page was loading it would appear on the screen as plaintext (or moreso
just unstyled/no formatting)... and once the page finished loading, it appeared
that a stylesheet was loaded, the page would reflow, and everything would look
as intended.  I hadn't meant to address the narrow-column issue, this was
something different and as dbaron pointed out, a bug had already been filed.  

In any case, I haven't seen this in awhile anyway - seems to have been fixed and
if I can I'll mark it closed.

Hm, I'll try to reopen and do WFM.
