163183 - inlines get preceding space(s) if inside a p::first-line in a table

Status: NEW

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

Description

[Kevin Cook]

In the first paragraph of http://www.lynuxworks.com/products/posix/posix.php3,
the <acronym> content "ANSI" seems to cause preceding spaces to be rendered for
no apparent reason.

->Layout.

This needs a simple testcase -> adding qawanted.

Attachment: Simplified testcase

A testcase showing a series of examples both demonstrating and avoiding the
reported problem.  Comments to follow.

According to my testcase, the problem only occurs if:

1. the element is contained within a table
2. the first line of the element has font- or text-changing styles applied to it
('font-weight', 'letter-spacing', etc.)
3. only affects the second-and-later inline in a line
4. a <br> element is NOT used to break up the flow of the element

Thus, changing the color of the first line doesn't trip the bug, even in a
table, but boldfacing it does.  Taking the exact same markup and moving it out
of a table fixes the layout bug.  Although I neglected to include a test for
this, removing the borders from the inlines with 'abbr, acronym {border: none;}'
did not fix the problem.

(Removing qawanted and confirming bug.)

Followup: converting the 'acronym' elements to 'span' elements didn't fix the
problem either, and I forgot to mention that ':first-letter' has nothing to do
with this bug, at least in my tests.  Altering summary to more accurately
reflect the problem at hand as I understand it.

Sorry for one more piece of spam-- adding testcase keyword since I provided one.

This worksforme on trunk as far as I can tell.
