Fiddle:

Issue:

When a field is invalid, the red underline appears in the field. When you hover over this field with the error, an error tooltip appears. If the field was in focus before, the tooltip popping up causes the field to lose focus.


Scenario (why it's annoying):

You type in form data, but a field has an issue. You select the field with an error to change it's value, but leave the mouse hovering over the field with the error. You go to type, but the tooltip pops up on a delay. Your field no longer has focus. So now you have to go back to the mouse to click on the field again.



Browsers:
Tested in the newest Chrome and Firefox. Also tested in yesterday's nightly extjs build.


How to recreate:

Run the fiddle. Select the field, then click outside the field, the red underline now appears. Click in the field to begin editing the value, making sure your mouse is still hovering on top of the field you just selected. Focus is lost before you can begin to type, causing you to have to select the field again.
