...and you're actually debugging the WASM executable which runs in a browser and not a native version of the application?

Not that it matters most of the time, I also do 99% of my debugging session on the native target. But for debugging problems that only happen in the WASM version actually debugging the WASM version makes a lot of sense, and that was anything but trivial not too long ago (if QtCreator can actually pull off a remote debugging session where the debuggee runs in Chrome then kudos to QtCreator).
