Created attachment 47468 [details, diff] a patch to fix
Created attachment 47469 [details, diff] patch to fix I make a mistake in previous patch,this is correct
It looks like this small change makes firefox render the page a bit worse than expected so we'll need to do some CSS fixes as well.
Some css elements need a bottom margin.
Fix has been applied. Thanks for reporting.
