File with two dots in name can be uploaded, but not deleted

Bug report

Summary

The MODX media-manager allows uploading of files with two dots ("..") in the filename,
but deleting it is impossible.

Step to reproduce

Create a txt-file with the name datei-mit_zwei..punkten.txt.
Upload it via media-manager. Try to delete it afterwards.

Observed behavior

Trying to delete it throws an error:

(the error says: "Please provide a valid directory")

Expected behavior

It should either not allow uploading such files in the first place, or if it does, make sure it can be deleted.

Environment

MODX 2.7.0-pl

Same story for files uploaded with "?" or "&" in the file name. Isn't there some way we can prevent bad characters from being used in upload file names?
