An issue with moving a file into a Cryptomator folder in MacOS using the Preview App

**OS:**
I'm using macOS 10.14.3

**Cryptomato version:**
I'm running Cryptomator 1.4.5

**Description:**
Steps to re-produce the error:
1. Save a PDF file in any folder.
2. Use the Preview app to open the PDF file.
3. Click File -> Move to ...
4. Select a folder mounted by Cryptomator (mounted by FUSE).
5. Click OK

What happened:
An error message appears, saying
" couldn't be moved because you don't have permission to access ".
And the file is not moved.

However, moving the file using the Finder App is fine.

Expected result:
The file is moved to the chosen folder.
