Issue description:

Pressing the TAB key while in the Grid (Crafting Grid in my case) shows a hovering text next to the cursor saying "Redstone mode - Ignore redstone signal". If you move the cursor over an item in your inventory, this hovering text remains and overlaps with the item's name.

For what reason are you pressing Tab in the grid? (if you use Tab to focus the grid the issue does not happen)

These are caused by Minecrafts accessibility feature switching between available buttons when you press tag. I don't think it would be a good idea to disable that.

I've just verified that this does occur with vanilla interfaces (the beacon to be specific), so indeed, this is not really related to Refined Storage.
That said, I will point out that TAB switching does not work properly with the Grid; the second press has the selection box grab input, and further TAB presses no longer do anything.

Yeah the default keybind to focus the textbox is tab. People who want to use it need to unbind that.
