Polylang breaks TinyMCE of PODS custom fields

[qx54]

Prerequisites

• This is not a usage question (Those should be directed to the community supported forum, unless this is a question about Polylang Pro in which case you should use the helpdesk).
• I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• The issue still exists against the latest master branch of Polylang and the latest WordPress version.
• This bug happens with only Polylang plugin active
• This bug happens with a default WordPress theme active
• I can reproduce this bug consistently

Steps to reproduce the issue

1. Install the PODS plugin
2. Create a custom post type
3. Add a custom field of the type WYSIWYG (Visual Editor) to the custom post type
4. Add a new entry (of the custom post type)
5. TinyMCE field cannot be access with the mouse cursor. (= actual behavior)
6. Disable Polylang plugin
7. TinyMCE field can now be accessed with the mouse cursor. (= expected behavior)

Also noticed that collapsing some metaboxes from plugins such as SEOPress doesn't work anymore. But this is only when editing a custom post type. When editing a normal blog post, collapsing the very same metabox works.

Thus looks like some conflict of Polylang with custom post types or the PODS plugin.

Do you confirm that this is the same issue as pods-framework/pods#5365 and fixed by the PR #369?

Confirmed, it's the same issue and fixed by the PR.

When applying the change the issue is gone and the UI works as expected.
