Problem with HTML tags < hr > < table > < details >

Hi!

I wanted to diversify my page by using some HTML tags and everything works in the editor, but when saved it is not respected and site includes plain text e.g. < table > < td >… or < details > < summary >…
I write an e-mail already to Patreon, but still didn’t get any answer after few days - so maybe, do you have any solution for this?

Take a look, I left uncommented < table > tags in the description and see how it is messed up :slightly_frowning_face: :

Have a nice day!
