I see that bug 124750 is fixed on the branch.
But it is still possible to focus a textarea in a background tab, see the URL
testcase. It consists of the following code:
<HTML>
<HEAD>
</HEAD>
<BODY>
<label>text<textarea>evil textarea</textarea></label>
<script>
function doe(){
var x=document.getElementsByTagName('label')[0];
var me = document.createEvent("MouseEvents");
me.initMouseEvent('click',1,1,window,0,0,0,0,0,0,0,0,0,0,x);
x.dispatchEvent(me);
}
setInterval('doe()',1000);
</script>
</BODY></HTML>

Reproducible: Always
Steps to Reproduce:
1. Open the url testcase in a background tab
2. Focus a textbox in this page
3.

Actual Results:  
Watch the caret disappear in one second or less

Expected Results:  
The caret should stay in the textbox.
Also happens with:
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.3) Gecko/20041021 Firefox/1.0

This one is especially bad because it KEEPS stealing focus, even after moving
away from the page. Yuck!
