Status: RESOLVED WORKSFORME

(Core :: Layout: Block and Inline, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; pl-PL; rv:1.5a) Gecko/20030718
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; pl-PL; rv:1.5a) Gecko/20030718

The following code acts strangely when the a-elements are being hovered.

<style type="text/css">
.t1 td a {
	padding: 0.2em 3em 3em 0.5em;
	width: 4em;
	height: 3em;
}

.t1 td a:hover {
	padding: 3em 0.5em 0.2em 3em;
}
</style>
...
<table class="t1">
<tr>
<td><a href="http://www.mozilla.org/" id="wt1">12345678</a></td>
<td><a href="http://www.netscape.com/" id="wt2">12345678</a></td>
</tr>
</table>

Putting the mouse cursor over and out of the <a> elements causes space between
them to increase. Longer text in <a> element causes the space to increase even
longer.

A testcase follows.



Reproducible: Always

Steps to Reproduce:
1. Open the testcase.
2. Put your mouse over one of the boxes
3. Put your mouse out of the box

Actual Results:  
The space between boxes increases.

Expected Results:  
The space should remain the same.

These Mozillas have been tested - the bug appears in all of them:

This bug appeared also in Mozilla 1.6.

But now, it's ok in Mozilla 1.7a and Firefox-trunk. This issue must have been
fixed with checkins to other bugs.

Resolving WORKSFORME.
