Office temporary lock files not cleaned up & wrong modification date

I'm not sure if this is a Winapps bug or where else to ask.

When I edit a file in Office, it creates a file starting with "~$" at beginning which is a lock file ("this file is being edited") that's normally deleted after you close the file.

(also note that the modification date is in the future)

However, when I run Office in Winapps this is NOT deleted afterwards. It is deleted just fine when using Office running in Wine/Crossover and also when running Office in a "normal" Windows VM (e.g. in Virt-Manager or Boxes) with access to the /home folder. Hence I'm opening the bug here because it seems to be Winapps-specific, at least for me.

My suspicion would be that there's something wrong with the way the Linux drive is mounted in the Windows VM. I'm using the Docker image for the Windows VM.

Start with the Docker image configuration and the Linux drive mount used by the Windows VM. Reproduce the Office lock-file behavior and inspect the resulting file timestamps; done means temporary "~$" files are removed after closing Office and their modification dates are correct.
