I had a similar problem while implementing buffer-local isearch-mode in
https://lists.gnu.org/archive/html/emacs-devel/2021-05/msg00490.html

The proposed solution was to put a special property on the symbol:

  (put 'isearch-mode 'overriding-keymap t)

Although it has limited applicability, I couldn't find a better way.
This might be ok for the isearch keymap, but definitely not suitable
for transient keysmaps that often are not bound to a symbol.

I confirm the patch fixes this bug report while keeping the test case
from bug#22958 working.  In any case this is better than hard-coding
special-handling of universal-argument-map.
