Confirming. (reproduced on Windows 98 with build 2000 050513)

Notes on testcase:
1. The problem seems to be caused by putting an IMG WIDTH="100%" inside a table 
cell with something else.  The image tries to be the size of the cell, causing 
the cell to expand, which makes the image bigger again, etc.
2. The image eventually stops getting bigger and suddenly disappears.
3. Replacing "foo" with "foo bar" makes each reflow push the table out more
4. The bug is reproducable 80% of the time.  Once it stops being reproducable, 
restarting mozilla makes it reproducable again.
5. Mozilla is still responsive while the table expands (some similar bugs have 
made mozilla unresponsive, see bug 30942), so this isn't a high-severity bug.

chris:  low priority, could you see if this is another incremental reflow "block 
max width" bug?

Comment 4

[karnaze (gone)]

Buster, in the attachment, the maximum width requested during the incremental 
reflow is not the same as the first unconstrained reflow. But an image is 
involved.

1) the image frame is broken.  it doesn't handle images with percent widths and 
fixed heights very well.  I have a fix for this now.

Comment 6

[buster]

along with fixes in incremental preferred width calculation, I also fixed some
image frame and image loader bugs having to do with images that have a fixed
height and a percentage width.
