path_maps path to a local symlink causes ignoring breakpoints, goes straight to completion

EDIT: I hadn't been able to figure out why breakpoints were being skipped when the vdebug connection otherwise worked properly. It turns out if a path_maps path contains a symlink, it will not work properly.

In my case, /var/www is a symlink to /home/derek/www

So this has the issue where breakpoints fail

let g:vdebug_options['path_maps'] = {'/var/www/local.laravel': '/var/www/local.laravel'}

And this works properly

let g:vdebug_options['path_maps'] = {'/var/www/local.laravel': '/home/derek/www/local.laravel'}

Below is the original issue as posted

Sorry if this is the wrong place for this but I don't know where this is failing. I have a successful connection and can step forward in the code. But setting a breakpoint then pressing F5 to go to the breakpoint (or disabling break on entry) will execute the rest of the code without hitting the breakpoint and I can't figure it out.

I've tried various versions of setting path_map without any success.

I am able to successfully configure xdebug without issue outside of Docker. Just when the image is running, the breakpoints don't stop despite being set. I've gone through old issues describing similar things but they seem to eventually reach the conclusion of it being fixed in a later version.

vdebug.log (I removed the lines for keymapper that severely bloated the output, if they're needed I can add them.
