2. make a selction in the first textarea
3. type LEFT (bug also occurs for RIGHT)

For testing purposes, this bug can also be reproduced on other platforms by
setting the pref "layout.selection.caret_style" = 2.

[Uri Bernstein]

As I wrote in bug 299417 comment 36, the current behavior (as described above) is consistent with the behavior in Safari and native apps. So we might want not to fix it unless Apple fixes the issue in OS X.

Note that determining the "correct" behavior becomes tricky when the selection starts and ends in texts of opposing direction (and perhaps even more so, in paragraphs of opposing direction).

Feel free to renominate if platform behavior changes.
