Desired Behavior

Prior to 28.0.1 I was able to manually mount /var/www/html/themes in my docker-compose file to modify certain files to update the default template. I would like this ability in subsequent versions.

Current Behavior

As of 28.0.2 and 28.0.3 it seems to be no longer possible to mount this path as a volume and make custom template changes.

Alternatives Considered

Not sure other than compiling my own image.
