Default HTML Viewer in Thunderbird - Can Not Change After Latest Update

The default HTML viewer in Thunderbird 115.7.0 (as of 24 Jan 2024) changed from Microsoft Edge to Mozilla FireFox 122.0 after an earlier Thunderbird update several days ago.

I went to Tools | Settings | General | Files & Attachments to change the HTML Content Type "Action" back to Microsoft Edge. There was no change to the setting. I then selected "Delete Action" to remove the HTML entry from the list. However, I can't add the HTML entry back into the list.

How do I add "HTML" back to the "Content Type" list and then select the HTML viewer that I want?

The Microsoft Edge browser default setting was changed by an unidentified process. Setting the default back solved the issue. Thank you.
