The page is closed, but the memory still exists

[runkobe24]

What is the current behavior?

In the vue3.x project, tinymce-vue is used. After the page is closed, the memory of tinymce-vue always exists and is not destroyed.

Please provide the steps to reproduce and if possible a minimal demo of the problem via codesandbox.io or similar.

What is the expected behavior?

In edge, Collect garbage can clear the closed editor memory.

Which versions of TinyMCE, and which browser / OS are affected by this issue? Did this work in previous versions of TinyMCE or tinymce-vue?
tinymce-vue: 5.0
vue: 3.4 / vue2.x
I have tried several versions of vue and they all have this problem.
