## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
Recently, we [fixed some issues with aria-hidden in
modals](https://github.com/ionic-team/ionic-framework/pull/30563),
unfortunately at this time we neglected modals that opt out of focus
trapping. As a result, a lot of modals that disable focus trapping still
have it happening and it doesn't get cleaned up properly on dismiss.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
We're now properly checking for and skipping focus traps on modals that
do not want them.

## Other information

I created regression tests for Angular in this to prevent this from
happening again. I initially tried to do this with core, but the issue
doesn't seem to reproduce with core.
