testcase

So far i was only able to reproduce the issue under Windows but the issue seems fonts specific (fixed width vs variable-width fonts maybe) so it is possible that with different configurations the issue will also reproduce under other OSs.

Test case attached + screenshot taken with Safari + WebKit-r71499.
Use the End key to get to the end of the Hebrew text (the left most position) and the caret will be painted over the last letter.

Using some other font size\combination of letters the caret can even paint before the last letter (which is very confusing) - screenshot of that case from Gmail chat also attached.
