120995 - <input onblur="this.focus()"> doesn't work, the focus is not set

Status: RESOLVED DUPLICATE of bug 109962

(Core :: DOM: Core & HTML, defect)

Description

[Martin Honnen]

Sometimes with form field validation you use onblur to refocus on the element if
it has not been correctly filled out for instance
  <input onblur="if (this.value == '') this.focus();">
This works in NN4, IE6, but with NN6.2 and Mozilla 0.9.7 it doesn't work, the
focus is simply set to the next element in tab order and remains there when you
tab out of the element.
As my test code shows the onblur event is fired, but for unknown reasons the
focus() call has no effect.
The test code also contains a workaround using setTimeout to trigger the focus()
call which works so it seems to be a timing problem.

Attachment: test case (tab to the first field and tab on, Mozilla allows it while NN4, IE6 keep the focus in the text field until you fill it)
