javascriptref.style.display='none'; on an INPUT element hides it happily, but
flipping disabled (to true and then false again) before setting display='none',
and then flipping disabled back to true causes the element to appear. Flipping
disabled back to false causes it to disappear.

Reproducible: Always

Steps to Reproduce:
1. In a page containing <input id='one' name='one' value='one'/>;
2. elt = document.getElementById('one');
3. elt.disabled = true;
4. elt.disabled = false;
5. elt.style.display = 'none';
6. elt.disabled = true;

Actual Results:  
The INPUT element reappeared.

Expected Results:  
The INPUT element should have remained hidden.

Attachment: Test case

This actually demonstrates the bug in my original context, using display: none;
to flip between two INPUT elements.

This almost certainly got fixed by the changes made in bug 171830.  I can
reproduce the problem with a 1.3-era build, but not with a current trunk build...

Confirm that I cannot reproduce this on 1.4a. Seems fixed to me.

Marking so.  ;)
