To reproduce this:

1. Turn on the Windows Narrator screen reader
2. Run HelloTextArea (in apps/toys)
BUG: the Narrator focus indicator will be drawn much larger than it should be, encompassing what would be the entire content rather than the visible portion.
3. Navigate to the TextField
4. Enter text such that there are more characters in the text string than can be shown
5. Select all text with CTRL-A
BUG: Once again, the focus indicator is drawn without being clipped to the visible text field control

This also happens with a ScrollPane with enough content in it to need the scroll bars. You will need to use the CAPS-LOCK left/right arrow keys to navigate.
