If you have top navigation enabled instead of sidebar then the iframe on the iframe embed page overflows the page resulting in a scrollbar, and if the iframe itself has it’s own scrollbar then this results in 2 scrollbars.
This appears to be due to the use of h-screen instead of h-full and the relative class being applied to some containers unnecessarily.
I can’t remember what I changed specifically when playing around in the dev console but the below setup fixes the issue:
EDIT:
Removing the relative class and changing h-screen to h-full on the section-iframe div + removing relative from the div underneath
fixes the issue - if you guys could update on your end that would be great
