User-Agent:       Mozilla/5.0 (X11; U; Linux i686; it-IT; rv:1.7.8) Gecko/20050517 Firefox/1.0.4 (Debian package 1.0.4-2)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; it-IT; rv:1.7.8) Gecko/20050517 Firefox/1.0.4 (Debian package 1.0.4-2)

The page reported in the URL make Firefox act in a strange way:
When the page is loaded it it displayed as expected.
But when i try to change font size for it (with CTRL + mouse wheel) the layout
get messed, if i reload the page it is display correctly.
If i chabge the firefox window sisze the pge is displated correctly.
I observed this problem on :
* FIrefox 1.0.4 on Debian
* Firefox 1.0.6 on WIndows
The same page seems to work properluy with konqueror.

The page is:

Reproducible: Always

Attachment: more reduced testcase

based on first testcase, lots of stuff removed. Doesn't look like 1st on load,
but after resizing.

Attachment: Even more reduced testcase

Showing that only one floating div is required.

Comment 6

[Uri Bernstein]

Notice bug 284019 which has a better summary but doesn't have a testcase and is
still unconfirmed.

Comment 7

[Uri Bernstein]

This is also very similar to bug 201215 (except the "percentage-width" part
doesn't seem to be necessary in this case).

Attachment: testcase using div and display:table rather than actual table

This is also reproducible using a div with display:table applied, rather than an actual table.

Oh, and I can reproduce this on both Firefox 1.5 and today's Camino nightly on Mac OS X (10.4.5).

replacing http://mypic.altervista.org/fire_bug/index.shtml as it gives a 404

the testcases are seen identical (not fixed) on Seamonkey and Firefox2

replacing URL again as it doesn't show the resizing problem this bug is about.
From a dupe I got the impression this bug was about the bug seen on en.wikipedia pages, but that seems to be bug 25888

the en.wikipedia URLs are displaying fine on Firefox2, but are shown broken on Seamonkey:

Seems fixed by reflow branch landing

Comment 14

[Steve England [:stevee]]

Weirdness observed with:
- Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9a1) Gecko/2006120606 Minefield/3.0a (pre-reflow branch)
(Resizing text on website forces a reflow and the layout gets all screwed)

No weirdness observed with:
- Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9a1) Gecko/2006120804 Minefield/3.0a1 (post-reflow branch)
(Resizing text on website maintains page layout as expected)

-->RESOLVED FIXED
