 We have a `die` with a message in case of a plugin activation failure
 here:
 https://github.com/Automattic/sensei/blob/1933acc544be8a98866bec1b8790a5b195d5b4c7
 /sensei-lms.php#L65.

 The message used to work until WordPress 6.3, and it stopped working.

 I think it was broken with this change:
 https://github.com/WordPress/WordPress/commit/768f51f60c308a06492dcda163b80c1c3ff6ebb9

 The reason seems to be because the iframe is now concatenated in the
 `$errmsg` variable, which is sent to the `wp_admin_notice`, and later it
 goes through the `wp_kses_post`, being removed.
