ALL MODULES DISABLED? true

Short Description of bug: When showing the players only an image that's pasted in a journal (not the whole journal page), they see only a blank window without the image.
Simple steps to reproduce the bug: open any image pasted in a journal page, show it to the players and check if they see anything.
Screenshots and/or console errors:

I'm experiencing this issue in Foundry 10.288 with dnd5e 2.0.3. I've attached a console image from a client that did not receive the images. A client connected to .localhost:30000 gets the images without issue. I was able to reproduce the behavior described above where the full journalsheet renders correctly but the imagepopout does not.

That's a big help, thanks, it's clear where the issue is now.

I saw something that looked like this in the release notes for version 290 with D&D5e; however, when I went to test it I got mixed results. Again, I tested with all modules disabled. This time, I was able to show players some of my journal images, but not others. Here is a screen shot showing an image shown (successfully), and image shown (failed), and another image shown (successfully). The images are all embedded images in a journal (different journals though). Seems like something is still broken.

This is from the client.

Do you have an excerpt of the <img> element in your journal that is failing to show?

I played around with the html and I found that the image displays properly when I use the relative link to the image. Below, the first tag fails and the second one works. I'm not sure why I ended up with a mix in my journals. I was just pasting images in when I created them.
