Embeding iFrame in HTML editor doesn't work because it turns < and > into shortcodes

So HTML editor turns < and > to shortcodes. Which is preventing me from adding an embedded map of the property to this doctype. Can I somehow force it to leave it as it is. It’s getting turned into shortcodes after saving the document. I tried forcing it with JS API and with Python API, but no success.

I’m guessing this is what you need to check.


Ah didn’t notice that.
Works great now.
