In `@classes/plugininfo.php`:
- Around line 231-235: Update the handling of font_size_input_default_unit in
the relevant plugin option metadata so a stored value of em is retained instead
of being skipped by the generic defaultsetting comparison; use pt as the
editor-facing default for this option while keeping the metadata outside config
unless settings.php is updated to accept it. Add a regression test covering the
stored em value.
