Thanks for filing this! Looks like it's an upstream issue: microsoft/vscode#131079

The VS Code regression is not going to be fixed anytime soon. I have added a temporary storage for images that gets wiped on extension activation which improves the situation for now: #2925

Using the repro steps above, I still get an error message on the left side.

Extension version v2021.8.36609

Looks like there's an issue with this when used with the Remote Repositories extension (as is the case with github.dev).

Verifier, please verify using desktop VS Code with a local repository (not using Remote Repositories). I will follow up with a bug with Remote Repositories.

This works if the PR is checked out. If it isn't checked out and you click on the image from the Pull Requests view, this error happens:

If this is "as designed" this can be marked as verified for now though

That is as-designed for now. Thanks for verifying!
