Status: RESOLVED WORKSFORME

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040707 Firefox/0.9.2

Pressing the ESCAPE key twice when a 'readonly' form element has focus renders 
it blank (see i.e. 
http://www.htmlcodetutorial.com/forms/_INPUT_DISABLED.html). This behaviour 
doesn't happen in Internet Explorer 6 and is not according to the W3C 
specifications (http://www.w3.org/TR/REC-html40/interact/forms.html#adef-
readonly). Javascript confirms the value of the form element is now "".

Additionally, in my own document, using:
<input onmouseover="alert(this.value)" readonly type="text" value="Algemeen">
yields the following error when "mouseover" event is triggered:

Error: [Exception... "'Permission denied to get property 
XULElement.selectedIndex' when calling method: 
[nsIAutoCompletePopup::selectedIndex]"  nsresult: "0x8057001e 
(NS_ERROR_XPC_JS_THREW_STRING)"  location: "JS frame :: <unknown filename> :: 
onmouseover :: line 0"  data: no]

Reproducible: Always
Steps to Reproduce:
1. Click on any readonly (INPUT) form element
2. It receives focus (it should) but is not editable
3. Press the 'escape' button twice
4. The form element is now blank

Actual Results:  
N.A.

Expected Results:  
Should have left the value of the form element intact!

Still happens with text fields that aren't read-only: bug 305272.
