Thanks, I totally missed this piece of news and have fallen to bias myself! I gave up monitoring Al Quds day in 2018 after making a complaint to the BBC that got a boilerplate response. I just don't have the time or the resources to do anything about it.
The open support for Hezbollah was there in 2018 and in previous years... but from 2019 the reports I've read, it seems like the police enforced the new law. I would need to make a freedom of information request with the police to see if there were any arrests to verify this.
