263265 - crash when applying nowrap to textarea holding long text strings

Status: RESOLVED EXPIRED

(Core :: DOM: CSS Object Model, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10

When applying the javascript whiteSpace = 'nowrap' to long text within a
textarea tag XP attempts to report a device driver failure as it falls over and
shuts down

Reproducible: Always
Steps to Reproduce:
1. Add a long text document to a textarea (20k will do it - dont know the lower
limit)
2. Apply the CSS 'nowrap' attribute to a javascript trigger
(obj.body.style.whiteSpace = 'nowrap')
3. Fire the trigger

Actual Results:  
XP will attempt to degrade gracefully as it falls over - may display the screen
in 640 x 480 with a warning that a device has performed an infinite loop
requesting a manual shut down.  Alternatively, the OP will simply shut down.

Expected Results:  
prevented the browser from performing word wrap within the textarea

The textarea tag performs a number of aberrant behaviours in firefox - this
example being by far the most dramtic I've experienced.  You do seem to already
have a significant number of bug notifications to this effect.  I suspect this
is an extension of a fundamental but underlying issue within the textarea behaviour.

Alexander: are you still able to reproduce this with a nightly build?
