test: Fix Rich Text failures (#60290)

* test: Define missing `logException` native module mock

Prevent cryptic test failure messages originating from invoking this
undefined method, which prevented the original error message from
surfacing in the test failure log.

* refactor: Export private API Rich Text module

This export was added for interoperability with the web version modified
in #58916.
