Asciidoctor.js error reporting not displaying on Windows

[danyill]

This extension is meant to support asciidoctor.js warnings and errors being reported in the text and in the "Problems" panel:

This is working for me on Linux using VS Code 1.61.1 but not on Windows at all as far as I can tell using VS Code 1.60.2. I have checked that "Asciidoc: Enable Error Diagnostics" is set (with setting: asciidoc.enableErrorDiagnostics), and that I am using Asciidoctor.js (with setting: asciidoc.use_asciidoctor_js).

I've found a solution, it appears intermittently on Windows and seems to be caused by the way we parse the filename which is not as per the extension examples.
