Unable to switch from sub to sup or vice versa in one click

[mudrd8mz]

1. Enable the sup mode
2. Type something
3. Click the sub icon

Expected behaviour: The mode is changed
Actual behaviour: No mode change. You have to return to normal mode first and then pick the format. Which doubles the amount of needed clicks :-p

p.s. This is not urgent at all of course. I just tried hard to find at least something to report here for this awesome plugin.

I thought that worked. It should. Hopefully we can fix it one day.
