"Share with Linux" option not available on Filesystem for Dropbox mounts

[domlayfield]

Now that Linux containers are fully supported on most Chromebooks, there's a feature where you can right click on a folder in the Files app, and choose "Share with Linux". Then when you're inside Linux, this folder is available in /mnt/chromeos/. Obviously, this is super useful for sharing files between the two operating systems.

For some reason, though, "Share with Linux" is not available for files mounted using the Filesystem for Dropbox extension.

Unfortunately, I don't know enough about Chrome OS internals to even start debugging the problem.

I want to have this feature working in order to have access to my Calibre datebase on Dropbox. I use Dropbox to be able tu use Calibre on more than a computer. It seems that it is possible when you pay for Dropbox. Is it true?

I don't think the problem is at the Dropbox end. I assume it's a question of whether ChromeOS exposes the API to this to "ordinary" applications (in which case a patch to chromeos-filesystem-dropbox would make it work) or whether Google considers this too risky.
