Bug 73573 – Typing in a text box doesn't work as expected after applying a non-matching css style rule

• Status: RESOLVED
• Resolution: WORKSFORME
• Component: CSS

[famlam]

(Doesn't happen in Chrome, fails in Safari 5.1.1 and 5.1.2 [didn't test other versions])

Reproduction steps
1. go to http://www.gocomics.com/peanuts-holiday-countdown. Log in with user: adblocktest password: abcdef
2. Type in the comment field: abc,,,cba (don't copy-paste: type)
3. paste the following in the address bar to insert the style element:
javascript:var c=document.createElement("style");c.innerText='div[style]{}';document.documentElement.insertBefore(c,null);
4. Repeat step 2

Before: 
The text shows up as expected
After:
The text shown in the textbox is "abc,cba"

Additional information:
- Adding the attribute 'type="text/css"' to the <style> element doesn't help
- The CSS selector doesn't match anything on the page. (and if it would, it doesn't add any rules, it's just {} )

OS: Windows 7 (but also confirmed on OS X 10.5.8)
Extensions: none

I cannot reproduce this with recent WebKit. Could you please test with a nightly build from <http://nightly.webkit.org/>?

Chances are that this has been fixed already, and Chrome just picked the fix earlier. In fact, this bug sounds familiar, but I cannot find it in Bugzilla at the moment.

Indeed, in r101559 on Windows (7 SP1) I cannot reproduce it on this site. Thanks!
(I wasn't able to test this in the two newer Windows builds as they fail to load the page).

Great.
