Problem catching enter/exit events and information of HTML Controls

[GoogleCodeExporter]

(GeckoFX v1.9)

In the I.E. Based WebBrowser control you can hook into the HtmlDocument 
LosingFocus and Focusing events, which can (just about) tell you which 
html controls were being moved in and out of so you can do some additional 
validation on their values. However, while I can find browser events in 
GeckoFX, I can't seem to find the equivalent document events (in fact any 
events) to get this info in GeckoDocument. I guess I could do something 
with the mouse positioning/clicking - but that doesn't tell me if someone 
is tabbing between fields etc. I tried hooking into the browser level 
GotFocus and LostFocus events but they don't seem to execute when just 
tabbing between fields.

Am I missing something here?
