Description André Dion 2011-03-01 08:10:23 PST
Using the test case here: http://jsfiddle.net/keeto/tqSyy/4/

When the field gets focus, an element is inserted into the DOM before it which causes the field to be pushed down, which in turn causes the field to "lose" focus. No blur event is fired, no typed text shows up in the field, and the field still appears to be in focus (the outline is drawn). Calling .focus() on the text field again has no result. The only way to re-establish focus is for the end-user to manually select the field again.

For historical preservation, I've created a stand-alone version of the test case <http://jsfiddle.net/keeto/tqSyy/4/>.

Work-in-progress layout test

Work in progress DRT/manual layout test.

I suspect that this bug is a duplicate of bug #14366. I will take a look later today unless someone confirms it before me.
