The problem only occurs when you click on text that was previously selected.

Case that works

1. Click on bar in the input.
2. Click outside the input to unfocus.
3. Goto step (1).

Every try after step (1): foo is selected.

Case that doesn't work

1. Click on foo in the input.
2. Click outside the input to unfocus.
3. Goto step (1).

Every odd try after step (1): foo is selected.
Every even try after step (1): foo isn't selected.
