31592 - Generated content on tag is repeated if tag extends to multiple lines.

Status: RESOLVED FIXED

(Core :: Layout, defect, P3)

Description

[Jesse Ruderman]

Open http://bugzilla.mozilla.org/showattachment.cgi?attach_id=6464 (bug 31588)
in mozilla and then open it in editor.  In editor, each line of text has 
a "named anchor" icon instead of just the first line.  In addition, the icon is 
drawn on top of the text.

Named Anchor should be automatically terminated.

The test case is technically incorrect HTML. The correct HTML syntax for named 
anchor should always have </a> immediatley following the <a>. 
There is a related bug on that issue (31594).
The behavior described here is a different problem: Since the tag extends
over multiple lines and has "before" generated content, it seems that content
(an image) should not be repeated on each line -- it should just be on just
the first line.
I'll let Troy triage to appropriate person.

Looking at the test case given below I don't see a problem with generated 
content. At least not when looking at it in viewer.

If you're going to assign it to layout, then I would appreciate a test case that 
exhibits the behavior in viewer

this is a layout problem. But since it's bad HTML, I'm leaving it for further
investigation later.

Comment 6

[Jeremy M. Dolan]

shouldn't this bug be blocking 31594, not the other way around? I think the
issue here is the auto-terminate certain tags (like <a name>).

Comment 7

For composer, this issue is no longer a problem, since we switched to using
a background image to represent a named anchor, not generated content using
the "before" selector. I constructed a test case anyway, and the problem has
been fixed when Marc Attinasi fixed the problem of images being repeated
when any inline style is broken into multiple display frames because of <br>.
I'll attach that test file.

Seems fixed.  The link in 
http://bugzilla.mozilla.org/showattachment.cgi?attach_id=6464 is now split into 
two links, one on each side of the table, in both browser and editor, but 
that's probably intentional.  An example:

<a href="http://bugzilla.mozilla.org">bug
<table border="1"><tr><td>&nbsp;</td></tr></table>
