Unable to resolve non-existent file. (Path mapping) #533

PHP version: 7.2.24-0ubuntu0.18.04.7
Xdebug version: 2.6.0
PHP Debug: 1.14.11

A previously working setup.
A remote apache web server.
A windows vscode client.
Remote source files are mapped to a local drive (y:) via webdav.

"pathMappings": {
"/srv/www/servernamehere/" : "y:",
}

Breakpoints are hit correctly but VS code cannot now open the source file...... Seems to be prepending where it thinks the local copy of the file should live.......
Unable to open 'EnquiryController.php': Unable to read file 'c:\Users\usernamehere\AppData\Local\Programs\Microsoft VS Code\y:\badger\controllers\EnquiryController.php' (Error: Unable to resolve non-existing file 'c:\Users\usernamehere\AppData\Local\Programs\Microsoft VS Code\y:\badger\controllers\EnquiryController.php').

Notice how the drive letter (y:) appears after the local store folder. The path after y: will correctly find my file.

Here is an example of a log from a debug session.
