Accessibility keys aren't correctly overridden by keybinds

The Tab key, in a container, selects the next item and the “browser back” mouse button (referred to in-game as “Button5”) exits containers

However, when the user binds hotbar slots to these keys, this feature should be overridden. The keys work as hitbar slot binds, but their accessibility functionalities persist.

For example (steps to reproduce):

• bind the back button to hotbar slot 1

• enter a container

• hover the mouse over any item

• press the back button

Expected behaviour: the selected item moves to hotbar slot 1, and the inventory stays open

Actual behaviour: the selected item moves to hotbar slot 1, and the inventory closes

Likewise for tab, using it as an hotbar slot hotkey causes the bind to be usable, but the tab functionality still persists, with the next item being selected

This same bug did exist in Java and was fixed in 1.16.2 (MC-145691)
