Just put a paragraph into a container.
Good catch! We’ve looked into this, and it’s an issue with Beta 11 (22896). It will be fixed in the next beta.
Those “guides” should only be shown when the Debug markers for Scroll effects is switched on.
For now just try and ignore them when previewing in Safari and know they will disappear with the next beta

None of my containers have the scroll effects enabled, but the markers are still shown in preview.

Yes, sorry, it’s a bug (they currently always show). It will be fixed in the next beta!
