Comment (by sainathpoojary):

 I investigated the root cause of this issue further and found that it
 occurs because the `tinymce-editor-setup` event listener is not registered
 before the event gets triggered. You can refer to the relevant code at
 this two places:

 https://core.trac.wordpress.org/browser/trunk/src/js/_enqueues/vendor/tinymce/plugins/wordpress/plugin.js#L21
 https://core.trac.wordpress.org/browser/trunk/src/js/_enqueues/wp/editor/dfw.js#L1468

 In contrast, when switching to text mode and then navigating back to
 visual mode, the behavior is different. While in text mode, dfw.js is
 called, which registers the tinymce-editor-setup event listener.
 Subsequently, when switching back to visual mode, the event listener is
 already registered, and triggering the event successfully adds the DFW
 button.

 A potential solution could involve ensuring that the event is registered
 before it is triggered or delaying the trigger until the registration is
 complete.

 I would greatly appreciate any input or suggestions to resolve this
 further. I also reviewed script-loader.php but could not identify anything
 relevant there.


 I have attached the video showing the event trigger delay:
