fix #1516: fix mouse-scrolling of overflowhandlers in firefox

Browse Source 
this is a workaround for scrolling in toolbars, etc. in firefox with the
mouse

while the result is not very "pretty", it maintains the old behaviour
for all other browsers and makes it work in firefox

we can drop this when we update to a new extjs release
