Can't expand text posts in some subreddits

[carlos-h-h]

Describe the bug
When the subreddit is set up not to have thumbnails, there's no way to expand text posts.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://old.reddit.com/r/TrueOffMyChest/
2. You can read text posts by tapping on the round "text" thumbnail
3. Now go to https://old.reddit.com/r/offmychest/
4. There are no thumbnails, and you can't read the text posts from the subreddit page

Expected behavior
Another "expando" button should be created when the self-with-text post has no thumbnail, to be able to read the posts' text from the subreddit page.

Note that in the original old.reddit.com, there's always an "expando" button for self-text posts, independent from the thumbnail.

Smartphone (please complete the following information):

• Device: Samsung S10
• OS: Android 12
• Browser: Firefox
• Version: 123.0.1

Additional context
I just want to express my thanks for this extension. Now that reddit definitely killed the compact layout, this is the next best thing.
