Be aware that if you run XDEBUG and try to generate MPDF documents it will always fail

I have found very strange behaviour when using XDEBUG and debugging is ON in Vscode. When I try to generate a pdf I always get this error Error detected. PDF file generation aborted: Undefined variable $e

When I turn off debugging in vscode strangely it works, I think it has something with xdebug session rewriting directory / file paths to when debugging session is on. I spent couple of hours on this looking for any errors so now I want to save other peoples time.

I'd be careful with the "always", code coverage for releases is run with xdebug and all test PDF generations end with no errors. https://github.com/mpdf/mpdf/actions/runs/8263060966/job/22603684101

Still I dont understand why when I run the xdebug session in vscode I get this error and when I turn off debugging it just works VSCode version 1.88.0-insider, WSL 2

xdebug config

{
            "name": "Listen for Xdebug",
            "type": "php",
            "request": "launch",
            "port": 9003,
            "xdebugSettings": {
                "max_data": 65535,
            },
        },

Unless you provide a full reproducible example, no one can understand either.
