215631 - Focus is stolen by input controls if another tab is open

Status: VERIFIED DUPLICATE of bug 124750

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Bernard Osmond]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030624

If you load the url in the background while viewing another page ( specifically
with another input field selected ( even better if you are editing it's contents
) ) the input on the form will steal the focus from the current tab. This also
happens with robotskull babble (
http://www.robotskull.com/robotskull/index.cgi?page=babble ). I assume that this
is a problem with javascript stealing the focus from other controls, but I am
not sure ( read : probably wrong ).

Reproducible: Always

Steps to Reproduce:
1. Load the given url ( or the robotskull babble one )
2. Switch to another tab ( specifically one with an input field )
3. Start typing in the input field.

Actual Results:  
When the gu page has loaded, the focus will be stolen from the currently selcted
input field, by the input field on the gu tab, and any text entered will be
shown in that field.

Expected Results:  
Input fields in background tabs should not be able to steal focus from the
currently selected tab. Instead their focus settings should be kept for when the
tab is brought to the foreground.
