## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

As part of https://github.com/ionic-team/ionic-framework/pull/27898 we
updated the radio and checkbox labels to wrap to the next line instead
of truncate. However, we did not consider long words. As a result, long
words run outside of the container.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- The radio and checkbox labels now break on words too in addition to
white space characters.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->

<!-- Any other information that is important to this PR such as
