[Possible improvement] Persist host paths for reverse mapping

[AnrDaemon]

Type: Bug?

I've stumbled upon a problem that, while understandable after investigation, could use an improvement.

My setup had included the following path mappings:

"pathMappings": {
    "/home/user/project": "${workspaceFolder}",
    "/home/user/project/app/admin/func/": "${workspaceFolder}/app/func/"
}

The project had a symlink from ~/app/admin/func to app/func at one point, thus ~/app/func/func.php and ~/app/admin/func/func.php were the same file. The symlink was made obsolete months ago and when I were doing cleanup of my dev. VM last week, I've removed it for good. After that, I've found that I'm unable to install breakpoints inside the ~/app/func/ directory. Even when I have a debug session in progress, and all paths are known to extension, setting breakpoint in the current file marks it as unresolved. Meditating over xdebug communication log immediately led me to the launch.json pathMappings setting, indeed, but I think this area could be improved from extension's side.
