[Bug] Uncatched error on code.pybricks.com on loading a block-code program with an unsupported block
Describe the bug Tried to load the program example for discussion #1558 on code.pybricks.com. The source uses an xbox rumble, not yet supported on code.pybricks.com. Results in repeated reloading of the panels. Hard to catch the error as it does not stay visible long enough.
To reproduce Steps to reproduce the behavior:
- Go to code.pybricks.com
- Load issue_1588.py (in my case)
- Select that source in the left bar
- See looping reload error
- Can select the source on the left side to delete, do get the confirm delete. But it does not go away.
Expected behavior What did you expect to happen instead? Maybe some simple user error: "feature not supported (yet)"
repair action I do not know how to recover from this loop 😢

The program failed to load. Please open an issue.
This is currently the expected result. It isn't supposed to endlessly restart, though.
In the long run, I'd like failed programs to automatically open in an archived version of the block editor, so you could never lose your programs. (As opposed to saying "heads up, couldn't open", as in the official app).
This is already happening in that you get the json instead of hiding it, but it isn't terribly helpful if there isn't currently away to open it in the visual editor.
The looping interface was worrying me. But time fixes it. So no worries.
What it should probably do in the future is:
- Explain that the program could not be opened and why (e.g. these new blocks not yet available)
- Generate a screenshot of the original program using the version of Pybricks Blocks that was used to create it, so you'd always be able to see the original and recreate in any version
