f2fs-formatted USB drive is read-only after filesystem creation

Description of problem:
I have tried setting up a f2fs USB with various methods (including GNOME Disks, KDE Partition Manager, gparted and mkfs.f2fs and the outcome is always a read-only USB

Version-Release number of selected component (if applicable):
f2fs-tools 1.8.0 (also tried on 1.6.0 with the same result)

How reproducible:
Format a USB drive to f2fs filesystem type and then try to write any file to it.

Steps to Reproduce:
1. Create a filesystem type of f2fs on a USB drive with any program e.g. gparted
2. Remove USB drive safely after creation and re-insert (to make sure the system recognizes it normally)
3. Try to write a file to the drive

Actual results:
The USB is read-only

Expected results:
The USB can be written to with any file

Additional info:
I've been advised that this bug has something to do with how KDE Partition Manager/gparted are not running chown on the USB drive after creation of the f2fs partition.
