[SOLVED] TinyMCE doesn't work within Bootstrap 5 modal

TinyMCE doesn't work within Bootstrap 5 modal

hope you'll be able to help me
so here is my problem:
I would like to integrate a TinyMCE editor in a Bootstrap 5 modal
But the problem is that in TinyMCE modals (for example link modal), I'm unable to edit the input. Here is my code:

</div>
        <script>
        tinymce.init({
                selector: 'textarea',
                menubar: false,
                height: '400',
                plugins: 'link',
                toolbar: 'link'
        });
        </script>
    </body>

You may tell me to do this: https://www.tiny.cloud/docs/integrations/bootstrap/
I already tried this solution, I did some tests and it only fix the problem up to Bootstrap V4.7.
I really hope you'll be able to help me, see you :)

Solution

Because of changes to Bootstrap 5, as OP mentions, the current fix on Tiny's documentation site (see here) does not work for Bootstrap 5 (At the time of posting, I can confirm that Tiny's documentation team is aware of this, and has an open task to address it in an upcoming docs update.)

Here is a workaround for this issue that:

Works in Bootstrap 5
Doesn't require jQuery
...doesn't work in IE11.

document.addEventListener('focusin', function (e) { 
  if (e.target.closest('.tox-tinymce-aux, .moxman-window, .tam-assetmanager-root') !== null) { 
    e.stopImmediatePropagation();
  } 
});
