Images on medium.com appear twice

[mikepqr]

Images in articles on medium.com appear twice in Reader view in Firefox. The first is blurred, the second is not. I don't know if this is the same root cause as #299 (medium.com doing weird stuff with lazy loading), but obviously the symptom is different, so I created a new issue. Please feel free to close as a dupe.

See, e.g. https://medium.com/mozilla-tech/revealing-arch-at-universe-29f4d00c9e58, which looks like this on Firefox 77.0.1 on macOS.

I'm seeing something slightly different, where the second image doesn't load at all.

The screenshots I'm attaching are the source and the destination, with the destination not having a src attribute on the second image.

Because of minimization there are no useful classNames or other attributes that we can rely on to remove the duplication. I'm not sure how we can fix this, other than trying to find a pattern with the DOM tree nodes.

This is now happening on the New York Times website too. I think this is new. See e.g. https://www.nytimes.com/2020/07/18/health/coronavirus-anti-vaccine.html. Please let me know if you'd like me to create a separate issue.

This seems to be resolved in the most recent release (the one that also includes an npm package). https://www.npmjs.com/package/@mozilla/readability
