RTL issue with first character

[whazor]

For now, it's the only thing that I saw.
Not sure if the "numeric column" also intended to be on the right/left side ( it's on the left ) - but it doesn't bother me much ...

meanwhile, i noticed another issue, not sure if it's for a another "ticket"
See this, I preload the text into the editor with .setValue(sometext) but then i start to delete the entire text (backspace) the first character remains, i cannot delete it.

The only way to delete it - is to "select all" (ctrl+a) and then delete...
Attaching image of the remained character i cannot delete:

I don't see something "special" when I request the value of the entire text, this is the only character remains ( no other hidden characters )
