Update keyboard when switching keyboards from Step One

Feature request: When the checkboxes under Step 1 are changed, switch the active keyboard to something newly available before leaving the screen.

I’ve been testing KAB, and I have 2 keyboards to install that the user can choose from.
Suppose the user choses one keyboard from step 1,

and continues on to Enable and Activate the keyboard.

If the user comes back later to switch to a different keyboard:

and then tries to type, the keyboard hasn’t updated.

They have to know to long-press (not short-press) the Globe and select the new option (which at this point is the only option because I unchecked the box).
