I just upgraded my WASM-project to .net 7 and now I cannot hit breakpoints if there are special characters in the path. Doesnt seem fixed, it worked in .net 6. See attached image, if I set a breakpoint I get a blank page and I can see weird characters when I hover the path.

Note: we use swedish characters throughout the codebase.
I got this error and if I renamed the file so that it didnt contain any "special" characters - then it worked fine.
