48375 - Left arrow doesn't scroll text area up properly

Status: NEW

(Core :: Layout: Form Controls, defect, P3)

Description

[[e-mail]]

BuildID:    2000080908

When the caret is at the top left corner of a scrolled text area (at the
beginning of a new line as distinct from a wrapped line) a left arrow moves the
caret to the end of the previous line but only appears to scroll the text area
up by three pixels instead of a whole line.

Reproducible: Always
Steps to Reproduce:
1. Type lots of short lines into a text area.
2. Cursor up to the first visible line.
3. Cursor left to the beginning of the line.
4. Cursor left again.

Actual Results:  The text area scrolls up three pixels.

Expected Results:  The text area should scroll up a whole line.

Almost any subsequent action will cause the text area to scroll properly.

Bulk move of mozilla1.0 bugs to mozilla.1.0.1. I will try to pull some of these
back in if I can.

still true, SM trunk.

As Neil says, "Almost any subsequent action will cause the text area to scroll properly" so what may be happening is until it hits the first "character" scroll uses some default font/character height.

I looked for related bugs without much success. Might this be related to bug 209073?
