Description mitz 2008-05-15 13:39:25 PDT
When the caret position is past the right edge of a block, it does not always paint (it paints when it moves or changes, but not when it should blink). This happens at the end of a line of right-aligned text (or the beginning of right-aligned RTL text).

To reproduce:
1. Open the URL
2. Click near the top of the document
3. Type some text

Probably a result of removing the padding in <http://trac.webkit.org/changeset/28523>.

This patch fixes the regression. Its weakness is that it only covers cases where the caret is within one pixel from the block, but I could not come up with a reasonable general solution. I am not sure that it is ever valid for the caret to be more than one pixel away from the block.
