I'm having issues with Redactor in Craft 3 as well. It will apply the format initially, but won't remove the format even with "type": "toggle" added to the "args".

For me, it doesn't apply any class

A class should apply to P tag but it doesn't.

Custom styles are a bit finicky in Redactor.

There will be a release next week that also updates the Redactor version - maybe that will help.
