Describe the bug All-in-one-seo causes double link insertion on classic editor "text mode"

What happened?

Since the upgrade from 3.4.2 all our sites are experiencing duplicated link insertion issue with classic editor plugins in "text mode" - It does not happen with Visual Mode.

What did you expect to happen? Single link insertion.

To Reproduce Steps to reproduce the behavior:

1. Go to 'Create a post -> Text mode tab on editor'
2. Click on 'Write some text in TEXT MODE - select text and click on "LINK" button'
3. Type in URL and enter
4. Link will be inserted twice like <a href="http://test.com">test</a><a href="http://test.com">test</a>

Expected behavior Insert only a single text such as <a href="http://test.com">test</a>
