And I agree that we should do something to fix this behavior.
But what to do exactly is not yet clear.

While looking at the tabs as frames grouped inside one frame, then
by analogy we could do the same how read-minibuffer-restore-windows
behaves in regard to frames.  After replacing 'C-x t' with 'C-x 5'
in your test case, I see that read-minibuffer-restore-windows=t
works inconsistently.  You can also try to change buffers
in both frames while the minibuffer is active.  Then exiting
the minibuffer does unexpected things.

So maybe tabs would need own solution, e.g. with a new variable
read-minibuffer-restore-tabs based on read-minibuffer-restore-windows,
or a new variable minibuffer-follows-selected-tab based on
minibuffer-follows-selected-frame.
