I'm nearly sure that this must be a dupe, but I've spent a whole lot of time
finding the right bug and I can't find it. Sorry.

At the demo URL, there is a comment added by one "Boris 'pi' Piwinger". The name
is a link and is italicized (<i>...</i>). The text of the link is empty from the
lowercase p to the end. You can make it appear by selecting the p.

The reduced testcase is: <a href="anything"><i>abc'pdef</i></a>. There must be
the apostrophe, the lowercase p directly following it, the link and the italics
(the <i> tag can also be outside of the link). It's very weird...

Reproducible: Always

Steps to Reproduce:
1. Load an HTML page containing: <a href="anything"><i>abc'pdef</i></a>

Actual Results:  
Link text appears as "abc'    " (there is underlined but empty space after the
apostrophe) unless you highlight text after the apostrophe.

Expected Results:  
Link text should be displayed as "abc'pdef".

Huh, this is weird. For the record, my default charset is ISO 8859-2, but
changing to 8859-1 doesn't help. What DOES help, though, is changing the text
zoom: increasing it from 100% to 110% or decreasing to 70% solves the problem.
Anything between 79% and 109% inclusive shows the bug. :-o This is a default
install of Win98SE Czech and Mozilla 1.3b. No special fonts or anything. I will
try a new profile but I doubt I did any relevant pref changes.

Attachment: Screenshot of another case

New findings: I attach a screenshot at 129% text zoom of another example, which
is at http://bugzilla.mozilla.org/show_bug.cgi?id=45375#c4 - the link's text is
"Peter ``jag'' Annema" - i.e., there are two back-ticks, the word "jag", and
two apostrophes. The text is invisible from the letter "j" to the end. The
trigger here is "`j", i.e. a backtick and a j. I found that an apostrophe and a
j also triggers the bug, but a backtick and a p does not (or, not at 100% text
zoom - it does at 150%).

Note that on this screenshot, the text is not completely invisible: at 129%
text zoom, it appears as a "dashed outline". Below that, it's invisible.

Tested also on a new profile (with the other theme) - same thing.

I am confirming this bug because I am most definitely seeing it, regularly. I
hope you don't mind me confirming my own bug now that I have the canconfirm
privilege.

Hey, you know what? It's fixed! :-o

No longer seeing the problem in either of the URL's I gave as examples, at any
text zoom between 40 and 180%. Should I just mark this FIXED, or would you like
me to investigate when exactly (between which two nightlies) the change
happened, so as to find what patch for what bug made the difference?

Don't bother. Thanks for the report though. I appreciate you tracking this stuff.

No problem, that's the least I can do. :-)
Resolving, then.
