raises-exception cell tag ignored in Jupyter Notebooks

[sterlinm]

Positron Version:

Steps to reproduce the issue:

1. Create a notebook with a cell that raises an exception.
2. Add the tag raises-exception to the cell.
3. Add a subsequent cell that does not raise an exception.
4. Restart notebook and run all.

Apologies, I'm not able to upload an example notebook.

Related, the visualization of cell tags appears to be inconsistent. If I create a new tag, I see it noted on the cell but if I open a notebook that has existing cell tags I don't see them. I haven't explored this as thoroughly.

What did you expect to happen?

The notebook should continue running after the cell with the raises-exception tag executes (and fails), so the next cell should be run.

Were there any error messages in the output or Developer Tools console?

Not that I saw.

I could reproduce this issue in Positron (i.e. the execution stops but it should continue with that tag assigned). VSCode correctly continues execution with that tag on the offending cell.
