I gave this some thought, and the selector validation that we're currently using (checking for a </style> substring) is insufficient to prevent a range of XSS attacks we might be vulnerable to. Here's a conversation I had with ChatGPT on this, which I believe could be a good starting point.

I'm interested to hear your thoughts on this, @AitakattaSora.

• Multiple selectors in a single rule
• Use htmlrewrite for contents replacement

@anfragment Thank you for your feedback. I have reviewed your comments and implemented the necessary fixes. Additionally, I removed unnecessary comments and renamed the function that checks for dangerous sequences in the selector.
