When I resize a textarea which is in a table by clicking on an image in the
adjacent cell, and my resize function changes the "alt" attribute of the image;
the enlarged textarea will overlap any existing elements below it.

This seems to depend on whether I change the rows attribute of the textarea
before or after changing the alt attribute of the image.  Attachment to follow.

Note: this may be related to bug 158296, but I'm not sure

Reproducible: Always
Steps to Reproduce:
1. Load the attachment
2 [review]. Click on the image next to "Bad" - the textarea will enlarge, but will
overlap the text input below it. Click again to restore.
3. CLick on the image next to "Good" - everything works fine.

Actual Results:  
The difference is in my resize function - if I change the rows attribute of the
textarea before I the "alt" attribute of the image, it breaks.  However, if I do
it in the reverse order, it works fine.  See the contents of the first if
statement in the "toggleDescSize_bad" and "toggleDescSize_good" functions.

Expected Results:  
either case should work.

Rob the rendering is identical for me whether I press the good or bad button.
Could you test it with a recent nightly?
