85012 - Each time the mouse is moved over a link a new line is added below it

Status: RESOLVED DUPLICATE of bug 71979

(Core :: Layout, defect)

Description

[Federico Giannici]

Every time the mouse is moved over a link or out of it, then a couple of blank
lines are added just below the link itself.

The bug happens for the links in the central part of the page I entered in the
above "URL:" field. I don't use Mozilla very much, so I dont know if this bug
happens somewere else...

The page doesn't execute any DOM code when mousing over the links on the page,
reassigning to layout for futher investigation. A simplified testcase would be
really nice to have. Marking helpwanted.

The attached testcase shows the problem. The table is kept to show that a
newline is actually added, but is not necessary to reproduce the problem.
Removing the <a> fixes the problem. 
The real problem is this:
br:before {
  content: "\a";
}
and if you put a br inside the link, it will add a new line.
Not sure whether this is a style system or a layout issue.
/me wishes glazou was available.
