Vertical Scroll problem whit Check Content Overflow

Hello team,

do I understand correctly that the option Check Content Overflow:
Is there for when a section is higher than the screen.
So that you can then scroll in this section?

As soon as I activate this function Check Content Overflow.
scrolling in the frontend is not possible.

I use the current WP version ELEMENTOR PRO with the new function FlexBox Container.

Here the data from the error console
Thanks Henk
