I made a twine, uploaded it to itch.io, and then tried to add the iframe to a Squarespace website but the scrollbar isn't in the embed. I already have the Enable scrollbar checked on the actual twine page on itch.io so I don't know why it didn't translate over. Is there a way to add a scrollbar to the embed information in order to force it to have a scrollbar. If someone could help me it would be appreciated. 

Thank you!
