Icons on hotkey doesn't refresh?

[Aceb]

Don't even know if we can call it a bug. And it is nothing that big.

If You fill a bucket with a liqiud and put it into hotkey, then it stays with the icon representing such liqiud despite it being change or empty.

For example: couple of times, had bucket filled with beer that I've emptied on occasions and filled it with water, wine or something. Icon on hotkey doesn't refresh, just stays whatever it was (beer in this case) at the moment of setting up the hotkey.

Feature, not a bug?
