In the _current_ main page of http://www.teledyn.com/mt/ (Jan 18 2004) the main
section of the page ceases to render after the item ":: The New Gleaners ::"
although view source shows that there are many items beyond that post, and the
entire page renders in Mozilla 1.5.  Since these items are all posted from the
identical template (MovableType) it is unlikely that the basic structure of the
page is corrupt (unclosed DIV or something) and an inspection of the source code
does not show anything peculiar, yet repeated attempts and reloads with 1.6
always ceases to render the page after this post.

Reproducible: Always

Steps to Reproduce:
1. load http://www.teledyn.com/mt 
2.
3.



Expected Results:  
see the same page in Mozilla 1.5/Linux

I will follow this post with an upload of the page source as seen by the 1.6
page-save.  This is a potentially serious bug since there is no indication that
content is missing from the page; an inexperienced user would simply conclude
that the page ended at that point.

Attachment: the current HTML for the page that triggers the bug

the HTML is perhaps not the culprit since the page when loaded without the CSS
is rendering the simple page in its complete form --- the CSS will be attached
later -- when viewed with the CSS, the page gets truncated at that same place.

Attachment: stylesheet that triggers this bug

This stylesheet rendered fine in Mozilla 1.5 and before, but mysteriously gives
up half way through the main blog content when seen in 1.6

Confirming bug, 2004-01-16-08 trunk Linux.

The relevant styling is: position:absolute; overflow:hidden; height:auto;
The computed height is ~2057px which is too small to fit the content.
(In Mozilla 1.5 the computed height is ~4015px)

More of the same issues with scrollframes -- the incremental reflow when more
content does not change the prefsize we got during the initial reflow.  We
should just have a bug to track this problem and mark all these as deps of it...

Regression occured between the builds 2003-09-15-22 -- 2003-09-18-22,
bug 69355 is in that interval.

Comment 7

[Boris Zbarsky [:bzbarsky]]

Right.  That's because we switched overflow:hidden to scrollframes at that
point.  Before that checkin, the bug was easily reproducible with
overflow:auto/scroll (try it with a 1.5 build).

OK, then the regression occured somewhere between Mozilla 1.3.1 and 1.4

Forget that,  I see now that it occurs all the way back to Mozilla 1.0.2

Just for the record, this bug persists in 1.7 RC1 just downloaded a few moments
ago.  Same test, same result.  I expect you already knew that :)
