Status: RESOLVED DUPLICATE of bug 216101

(Core :: XUL, defect)

I discovered that if you enter a lot of single character lines in a multiline
textbox, and then use backspace to erase the lines, the cursor leaves copies of
itself on the single character lines. Note that if I alt-tab to another app that
obscures the textbox, or switch to another tab withing the browser, then return
to the page with the textbox, it appears correctly without the droppings.
Probably a minor rendering bug with the cursor.

Reproducible: Always
Steps to Reproduce:
1. make a multiline textbox, say 10 rows by 80 cols
2. enter a bunch of lines with only 1 character
3. starting at the very end of the entered text, press and hold backspace key
down. As lines are deleted, you'll notice how the cursor leaves copies of itself
on previous lines.

Actual Results:  
Cursor leaves 'droppings' on deleted lines

Expected Results:  
Shouldn't see those droppings at all =)
