When we switch blocks from inventory to hotbar the mouse browse overview didn't refresh until we actively select the slot of the hotbar. (I didn't tried in crafting mode nor to move blocks from slot of the hotbar to another slot)

Here the 3 multislot of Dark Grey Armor (Dark Grey Hull + Dark Grey Standard Armor + Dark Grey Advanced Armor)

As you can see I have then switch that set with the White Armor one, but the browse overview still indicate information about the Dark Grey stuff.

It's quite trivial when you use clear different blocks where the fake information is clearly unmasked, but it's become tricky when you use the hull/armor blocks. specially when you switch between blocks from the same set of color. It already trick me severals time ; i.e. put surface with Black Standard Armor instead of Black Advanced Armorand and found the texture look weird only 10 minutes later. Sometime reflection prevents to visually recognize the blocks (i.e. white and yellow set of armor when expose to sun light) so you'll rely only on what hotbar say.
Moreover it can also confuse the non-english speaker (specially the one who sucks in English) and lead them to learn wrong name for wrong blocks.
