Hyperlinked Texts Look Like Un-Hyperlinked Texts in Visual Editor

Hi. In the visual editor, texts that are hyperlinked are formatted nearly identical as normal text. On the frontend, the hyperlinked texts are looking just fine, with underlines etc. But, in the visual editor, I cannot tell which texts are hyperlinked. See https://screencast-o-matic.com/i/c0eZreV4Wkn. The left side is the page on the frontend, and the right side is the page in editor view. Note that “denatures protein” is formatted correctly on the frontend. How can I make the hyperlinked text in visual editor visible (without changing the way hyperlinked texts look on the frontend)?

If you need login info, let me know.

This is my first time posting, so I'm not sure if I was or wasn't supposed to add to an old post by someone else or create a new one. I decided to open a new one because it's been almost a year since the post on the same topic initiated by someone else. So, you can ignore my message on this post:
