File::canView() doesn’t take session grants into consideration

[kinglozzer]

This is more of a query than a bug report, but if a user is granted permission to view a file via the session grants functionality, canView() still returns false. Should we ensure canView() returns true in this situation, as the user can access the underlying file?

My specific use case is users uploading to a protected directory. We grant them access to the specific file they’ve uploaded via session grants, but not other files. FileUploadReceiver checks canView(), which will return false. We can achieve the above suggestion with an extension, but it struck me as odd behaviour
