This bug contains two issues - First. press the left arrow key from the second line move the caret to the middle of the line instead of the end of it. -- this problem is because webkit lacks of one-to-one correspondence between visual and logical character positions. 

The second issue is unable to place the caret in the RTL text in the first line by using mouse click -- I have created a separated bug 105451 and submit a patch for it.

> Steps to repro:
> 1. Put the caret in the second (empty) line
> 2. Press the Left arrow key
> - the caret will appear in the middle of the line instead of at the end of it. 
> 3. Try to place the caret in the second part of the line using the mouse
> - that part of the line is not "clickable"
> 
> There is also the symmetric case using RTL textarea and LTR Override Character.
