Live reload isn't picking up file changes inside a containerized dev environment

A developer bind-mounts their source folder into a container for hot-reload, but changes made in their IDE aren't reflected. What would you check? Expected reasoning: confirm the bind mount path is correct and the container process is actually watching the mounted path (not a copy made during image build that shadows the mount); on Docker Desktop for Mac/Windows, check whether file-change notifications are being properly forwarded across the VM boundary — some dev servers need polling mode enabled in this case.
