Tag Browse Filter Not Working on Remote Provider

Running script in Ignition Version 8.1.31
Remote gateway is version 7.9.21

I am trying to run system.tag.browse on a remote tag provider and filter by Folder. This seems to always return everything under the given path regardless if it's a folder or not.

Example script running in script console:

results = system.tag.browse('[RemoteProvider]Path/Path/Path', filter = {"tagType": "Folder"})
for result in results:
	print result
