Summary: When highlighting PRE-formatted text, any line of text that appears below a blank line will have a selection area twice as high as the text itself. Steps to Reproduce: 1. Open test case attachment. 2. Highlight "Line 2". Expected Results: Highlighting "Line 2" should only highlight the height of the text. Actual Results: Highlighting "Line 2" highlights twice the height of the text. Regression: This also occurs in Mac OS X 10.4.3 with Safari 2.0.2 (416.13). Notes: - Firefox 1.5 (Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8) Gecko/20051111 Firefox/1.5) does not exhibit this behavior on the same test file. - In Firefox, user is able to select the carriage return in the blank line by click-dragging the mouse from after the last text on "Line 1" until before the text on "Line 2". This is not possible in Safari, although it may be a different issue.

This is > not possible in Safari, although it may be a different issue. Ignore this comment--it's not true. I can select the carriage return by itself this way. It's only the highlighting that is the issue.

Another good example of this (where the highlight is about 5x too tall) is in the Bugzilla bug mail: http://www.opendarwin.org/pipermail/webkit-unassigned/2006-January/001427.html Try highlighting text on this line on that web page: ------- Additional Comments From ...

I think bug 8333 is a duplicate of this bug.

(In reply to comment #4) > I think bug 8333 is a duplicate of this bug. Good catch! I'm going to mark this bug a dup of bug 8333, though, since there's a lot more implementation detail in that bug than in this one. *** This bug has been marked as a duplicate of 8333 ***
