You may be totally right. I think I misunderstood how the plug-in works in relation to my WordPress Media settings. I’ll mark this as Resolved. In the meantime, I hope my responses below might help:

First, does the above explanation make sense explaining why the plugin is responding as expected?
Yes. The comments explaining what is going on in that moment are very helpful. I found the mention of HDPI screens, and how they play a role. I think it can be easier to forget that detail or understand how it has an effect, especially since it’s not super-obvious in the inspector.

Second, are there any places in the documentation that are confusing with regard to what to expect from the plugin?

In the headline “WordPress Image Classes”, on the plugin page, I think it might help to mention where these image sizes you mention originate from. In other words, I think mentioning that the image sizes are set in Media (and not by the plugin) could be helpful thing to note, especially if those Media settings had been altered by a previous admin and causing some oddly-shaped images to be created.

Perhaps a “How the Plugin Works” area or something similar. It really helped me when you explained what it was doing.

Finally, are there places in the documentation that should be expanded or contracted to improve clarity?
My response in the previous question should cover this one.

Thank you for sticking through this thread with me. 🙂

That’s a pretty good theory. I’m viewing this on a Apple Thunderbolt Display. I’ll check out your branch later this evening and update this thread on the result. Thank you for looking into this!
