Hi,
When the Enpass Extension is installed in Safari, It is no longer possible to access the tinyMCE editor.
You can check it on this page: https://www.tiny.cloud/docs/tinymce/6/full-featured-premium-demo/
The editor does not finish loading and cannot used. Several errors are visible in the console.
Tested on Safari Mac 17.1, MacOS 13.6.1
