Issue description
The inventory list on the right partially ignores when the game window gets resized.
It should switch to multi columns. It does remain centrered, though.
There is a work around, add/remove an item. That triggers to resize the inventory.
Expected behavior
Inventory should switch between 1 and 2 (, 3...?) columns depending on window height. Apparently the window resize event is not fully handled.
Reproduction steps
Reduce window height until inventory is too tall.
or
Increase window height until space is enough for single column.
Game version
v0.4.12e
