299527 - BiDi: In an RTL textarea, pressing DownArrow moves the caret to the end of the text (in lines that end with an RTL character)

Status: VERIFIED FIXED

(Core :: Layout: Text and Fonts, defect)

Description

[Prognathous]

To reproduce:

1. In the first textarea, put the caret in the first line, then press End.
2. Press the DownArrow key.

Actual Results:  
The caret moves to the end of the text (line #4)

Expected Results:
The caret should move to the end of line #2

The opposite happens if you put the caret after the last letter (line #3) and
press the UpArrow key - the caret moves all the way up, instead of to the end of
line #2.

- The bug doesn't happen if the line ends with an LTR character (e.g. a Latin
character)
- The bug doesn't happen in LTR textareas

Mass-assigning the new rtl keyword to RTL-related (see bug 349193).
