Linktext with formatting (<sub>) is split into separate links

CO2-Steuer as linktext results in:

<a href="#link">CO</a><sub><a href="#link">2</a></sub><a href="#link">-Steuer</a>

Hi @mlinhuberin. I was not able to reproduce this using the classic editor or the block editor.

This is what I did, with the block editor enabled:

1. Created a new post.
2. Typed CO-Steuer.
3. Selected CO and toggled on Subscript in the More rich text controls menu.
4. Selected CO-Steuer and created a link using the Link button in the toolbar.
5. Opened the Code editor.

This is what I did, with the block editor disabled:

1. Created a new post.
2. Opened the Text view.
3. Manually replaced CO with <sub>CO</sub>.
4. Opened the Visual view.
5. Selected CO-Steuer and created a link using the Link button in the toolbar.
6. Opened the Text view.

In both cases the markup was <a href="http://example.com"><sub>CO</sub>-Steuer</a>.
