Issue carried forward from comments in bug #31814...

When using drag&drop there is always a square box outline attached with the
cursor until drop.  This happens on single or multiple selections.

1.  Open mail window, open a mail folder.
2.  Select a single message and drag it to another folder.

Result:  there is a square box outline attached to the cursor as it drags.

in order to fix this, we have to know the location of the frames from JavaScript. 
Since this info isn't available, I'm not sure how to fix this. The square box you 
see is a placeholder, and debug builds issue a warning that a region isn't being 
passed.

The JS writer has to create this region, but we don't have the ability to do this 
yet.

I don't have permissions to set bug dependencies, so I'll remark here that this 
bug should be dependent on bug #34938.

This bug should not be dependent on bug #32169 because getComputedStyle() does 
not return pixel values for left,top,width,height.  It only returns whatever 
CSS values have cascaded, which could be "auto", "50px", or "50%".  

What you are looking for here is guaranteed pixel values.  You can get those 
values from the properties offsetLeft, offsetTop, offsetLeft, offsetTop.  These 
properties were buggily implemented, and don't work right yet.  See bug #34938 
for a description of the problem, and bug #9844 for the original bug.

Whoops... stupid me. I meant bug #34398...  I guess I can set dependencies, I 
just had the bug # wrong.
