User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Galeon/1.3.21 (Debian package 1.3.21-1+gnome28+1)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b2) Gecko/20050616 Firefox/1.0+

Attaching testcase.

When a line-height is specified, the borders of elements with -moz-border-radius
specified are rendered incorrectly.  When a line-height is not specified, the
borders are rendered correctly.

In the testcase, the span's bottom border is not wide enough.  Here, line-height
is specified for the body, but the problem also occurs when line-height is
specified for the span.  Here, line-height is specified as a number, but similar
problems occur when it is specified in ems or as a percentage.  For some font
sizes (when changing with Ctrl +/-), the problem is not evident.

Reproducible: Always

Steps to Reproduce:
1. Open testcase.html.
2. Adjust font size using Ctrl +/- until border rendering problem is evident.

Actual Results:  
Border rendering problem is evident.

Expected Results:  
Rounded border should be rendered correctly.

Same rendering problem occurs with Mozilla 1.8b2, build 2005061502.

Rendering appears normal in Firefox 1.0.4 and Mozilla 1.7.8.

Confirmed also in OS/2 DP nightly. In w32 DP nightly, misrendering occurs
whether or not line-height is specified.

Andrew, do you still see this? This worksforme as far as I can tell...

Attachment: screenshots

This is what I get with trunk builds 2005100503 (gtk2) and 2005100405 (gtk1)
(differences due to font size, I guess).
With gtk2, the bottom border is flat (no rounded corner).  With gtk1, the top
and bottom are the same, but the left and right differ slightly.

Current Cairo builds do show the attachment correctly (as far as I can see), so marking this one as FIXED by bug 368247
