312718 - First line in absolute positioned <div align="right"> aligned incorrectly

Status: RESOLVED DUPLICATE of bug 132561

(Firefox :: General, defect)

Description

[xebra314]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7

This is rendered incorrectly:

<style>
.topright { position: absolute; top: 3px; right: 3px; }
</style>
<div align="right" class="topright">
blah
<br>blah2
</div>

It should appear as:
_____
 blah|  <-- Right edge of browser window
blah2|

But it appears as:
_____
blah |
blah2|

Whereby the first line is offset by a &nbsp; for no apparent reason.  You can
highlight the extra &nbsp;, it is actually there, though it is not indicated in
the HTML source.

Note that if you change

blah
<br>blah2

to

blah<br>
blah2

within the <div>, it is rendered correctly, without the mysterious &nbsp;.

Reproducible: Always

Steps to Reproduce:
Copy this HTML into a blank file.  Open it with FireFox:

<style>
.topright { position: absolute; top: 3px; right: 3px; }
</style>
<div align="right" class="topright">
blah
<br>blah2
</div>

Actual Results:  
_____
blah |  <-- Right edge of browser window
blah2|

Note the erroneous &nbsp; at the end of the first line.

Expected Results:  
_____
 blah|  <-- Right edge of browser window
blah2|

Changing

blah
<br>blah2

to

blah<br>
blah2

causes everything to render correctly, the mysterious &nbsp; disappears.  It's
still annoying though.

Probably, you're experiencing bug 132561.

Peter van der Woude:

If WFY because you didn't bother to read the bug report.  Notice how your 
source matches the source of the WORKAROUND, which, of course, was designed to 
NOT EXHIBIT the BUG.  Next time, try looking at the source of the ACTUAL BUG, 
and not the WORKAROUND.

Martijn Wargers:

The problems appear different to me.  None of the test cases in the bug report 
you linked to exhibit this problem, while the source given in this bug report 
does quite clearly exhibit this problem.  The bug report you linked to is 
concerned with inappropriate alignment, while this (somewhat inappropriately 
named) bug report is concerned with the spontaneous generation of a   
that appears nowhere in the HTML source.  To clarify: there is no whitespace 
between the end of line and the <br>, but FireFox spontaneously generates a 
&nbsp;.

Reporter, could you test this in 1.5 beta 2? There's been about a bazillion
layout bugs fixed since 1.0. I'm not seeing this in the current builds.
