ColumnResizer's resize bar isn't visible outside of the dgrid area.

In chromium 18, possibly others
When using the ColumnResizer extension, I click and drag the resize handle for a column all the way to the right of the window (outside of the dgrid's box) and I don't see the resize handle bar anymore, but it's still being dragged.

Also, If I drag all the way to the edge of the browser window then back into the window, the resize handle looks to be offset from my cursor, it would be nice if the resize handle bar always followed the cursor correctly.

Related: sometimes the resize handle gets stuck in dragged mode until a click happens, when the cursor leaves the widow, is released, then re-enters the window.

Related issue: The Resize Handles don't work well with Dialogs being shown on top of them.
Specifically, a dgrid with a Dialog box on top of it (in whole or in part) still shows the resize handle cursor and the resize handles react to DnD.
