58827 - empty inlines in empty blocks get no border [INLINE]

Status: RESOLVED WORKSFORME

(Core :: Layout, defect, P3)

Description

[Hixie (not reading bugmail)]

STEPS TO REPRODUCE:
   <div><span style="border:solid"></span></div>

ACTUAL RESULTS:
   Nothing is displayed.

EXPECTED RESULTS:
   A vertical line with the height of the font's ascent/descent, the colour of
   the 'color' property, and the width of twice the 'medium' border size.

See attached testcase. Spotted in the second test of section 5 of:
   http://www.bath.ac.uk/%7Epy8ieh/internet/eviltests/lineheight3.html

It works fine if there is any text in the <div>.

Attachment: Simple and self explanatory testcase. Output should be green, not red.

Sounds like it could be an emptiness check done the wrong way... (or is it wrong?)

Using Mozilla 0.9.1 (Build ID: 2001060713) on Linux, this problem looks fixed. 
The first test case (test2,section5 of lineheight3) is showing a vertical aqua
bar.  The vertical bar looks vertically centered around the horizontal zero
height box. In the second test case (id=18521) the output is green not red.
Is this still a bug?

Hmm. Wow. Indeed.
Well, that's cool.
Anyone have any idea what fixed it?
