TAB as inventory button does not fully work

What I expected to happen was...:
When i assigned the "Open inventory" function to the TAB key, i thought it would behave like it does when assigned to any other key, by opening player inventory, closing player inventory and other inventories like chests and hoppers, and some other functions im probably forgetting.

What actually happened was...:
While using TAB as the inventory opens the inventory, it does not close anything, making it so i have to use the Esc key to close an inventory

Steps to Reproduce:
1. assign the "Open inventory" function to the TAB key

2. Open your inventory
3. try to close your inventory using the TAB key.
