[RP] escape key in moz

[Campbell]

Hi again, odd thing I noticed which I'm not terribly concerned about, just
find interesting...

I've got a late-ish mozilla build, set up to search from the address bar.  
When the list box containing 'search Google for ...' is dropped down, my
escape key (currently M-a) simple selects the whole text field, as if it
was not a very important key combination at all.

Any obvious (to someone else) reason for it?

cheers
