I tried out the extension for use with debugging Swift code compiled to Wasm in debug mode running in Node.js, then used chrome://inspect to attach the dev tools debugger to the Node.js process, but unfortunately it doesn't seem to be working.
When I step into the Swift code I don't get source maps at all, so I see just the wat text.
Whereas in VSCode I do get source maps, but, I of course don't get your enhancement (which is expected) but shows that it is compiling in debug mode with DWARF:
Is this a known issue that it can't work with Node?
