In page editor create section, in it advance settings go to wrapper -> Layout -> [ Display -> flex & flex direction -> row & align items -> stretch
add two divs to that section.
to one div add some content.
to second div add picture/loop builder/any other widget.
to picture/loop builder/any other widget set height to 100% (where you can find that setting because everything by default has min height setting,
you see that widget not stretching to container height. ( loop building reacts only to custom css where ee-posts or ee-posts-list is set to height: 100%.
parent div wrapper layout is flex, align items is set to stretch.
loop builder wrapper size height is set to 100% ( and in editor it actually streches to parent height)
adding custom code to ee-posts or ee-posts-list container solves problem.
the same problem with image widget - it ignores height setting - 100%
it solves only with custom css in figure, breakdance-image-container, breakdance-image-clip - height: 100%
