Description Darin Adler 2005-06-25 12:14:13 PDT 
Like other editing systems on Mac OS X, WebKit should display a split caret when on the boundary 
between a LTR and RTL run.

The high caret is the "primary caret" and corresponds to the place the caret would be for the base writing 
direction. The low caret is the "secondary caret" and corresponds to the place the caret would be for the 
other writing direction.

I've got a patch in the works that implements this.

Bug 3729 talks about a related issue, making the right and left arrow keys do the right thing in RTL text.

I started working on this bug and on bug 3729 (starting with the latter), ressurrecting bits from Darin's patch. I am changing inlineBox() so that for "primary" it will always return the box whose direction is the same as the base direction, for both edges. That seems to work well. I also think that as the "base direction" you should take the direction of the block, which is not necessarily the same as the RenderText's direction, but I still haven't changed that.

The bug the 22386 is Windows counterpart of this bug.
