I love how simple this change is now after the redesign.

Shame it doesn't appear to work now I'm adding a test for it!

Ah no, I forgot the recent changes only fix this issue in Node v20+ 🤦🏻♂️

Closes #13416
Another way to fix this issue would be to check via the debugger if the property exists already on the error object and bail early before we have local variables. However, this would add an extra round trip call via the debugger for every error. Since re-thrown errors are far less likely, I decided instead to just not overwrite existing local variables.
This PR also adds a
Debugger.resumecall in the catch case to ensure that they debugger will always resume even if we get errors while debugging.It's worth noting that this only fixes the issue in Node v20+ where we use the async debugging interface.
