Problem with dynamic height elements inside Vertical Layout Group

I have a Vertical Layout Group that I want to populate with an array of elements. The element consists of:

• Text A: stretch all, X: 0 - 0.7

• Text B: stretch all, X: 0.7 - 1

• Image A: horizontal separator line. Anchored to Y 0

The problem: Both Text A or Text B can span multiple lines. I want the element (e.g. the parent of the 3 elements above) to have the minimum height required to accommodate the bigger of the text elements (shown to the right; the second element is longer than the others).

The usual "Content Size Fitter + Hor/Vert Layout Group on Parent" trick doesn't work, since it overrides the stretch all anchoring of the 2 text elements, thus leading to inconsistent layout inside the list.

I tried several other approaches using Content Size Fitters, Layout Elements and Layout Groups, but couldn't get a satisfying result.

Would be glad if anyone has found a solution for this or similar situations.
