This why Safiur asked to disable the mouse wheel on read-write combo-boxes.

I have just tested a read-write combo-box in Kate:

- Mouse wheel is not disable, it scrolls the items, erasing what you 
have types in the combo.

- It does not support high resolution mouse wheels, a bug I have fixed 
in the same commit where I disabled the mouse wheel.

So I don't know what to do.

I understand that changing the contents of a read-write combo-box with 
the mouse wheel inadvertently is disturbing, but apparently this is how 
it is already implemented in Qt. As for GTK+, I don't know.
