Two lines of red moving text above the yellow "Hallo...uuuund Herzlich
Willkommen..." line are displayed only with a width of 1 pixel at the very
beginning og the lines. They should travel over the whole screen width.

Reproducible: Always
Steps to Reproduce:
1. go to website
2. watch
3.

Actual Results:  
moving text is illegible

Expected Results:  
moving text should travel over whole screen width

The bug also appears in firefox. I'm not sure about the right "component". Text
lines display correctly in all non-Gecko browsers.

is this a regression or have we always had this problem?

There is no problem in mozilla created by MOZILLA_1_6_BRANCH.

This is a MARQUEE problem. The marquee is trying to find its width and returning
1. I don't really know how marquees are supposed to work...

I'm not sure. I first noticed it after going from 1.4 to 1.6, but that may be a
coincidence.

You can see the same thing at

Only this time the upper line shows okay, the lower line is truncated.

I've investigated further into this and found that if you remove some mouseover
things from the source code of the page and reload it into Mozilla, the marquee
will display okay.

<p><b><u><span onmouseover="Bild.style.visibility='hidden'"
onmouseout="Bild.style.visibility='visible'"><br>
<marquee><font face="Verdana" size="3">
<p><b><u><font color="#ff8c00">Am Sonntag findet vorraussichtlich endlich der
Starchat statt! Von 18-19 Uhr wird Ronja euch alle Fragen beantworten
=)</font></u></b></p></font></marquee><em><font face="Comic Sans MS"
color="#f0c00a"></font></em></span></u></b></p>

We could really use a reduced testcase here!

Looks like the enclosing <span> is confusing the marquee when the marquee looks
at its ancestors to try to get its width.

If you replace it with a DIV, the bug goes away. So this is related to
block-in-inline. Fun!

Attachment: *very* reduced testcase

Here you go. It's very simple. A marquee inside *two* inline elements goes
wrong. If you remove one level of SPAN then it's OK. Over to you Doron...

Sorry, it has checked that a problem occurred also in this build by the test case.
Since the page of the URL point has bad use of color to an eye, I have not
noticed like the point...

This is fixed by the cleanup marquee bug
(http://bugzilla.mozilla.org/show_bug.cgi?id=167224), which needs sr.  It redid
the width calculation.

Roc, wanna sr? :)

I'm not really a wizard with JS/XBL. Try to find someone else to sr if you can,
please.

Seems to work fine now.
