How do I get a parent controls height to adjust dynamically in power platform canvas app?

Question

I have a horizontal container, which contains a number of labels with a specific width. The labels Auto height is turned on, so their height auto adjusts to the content.

My Gallery represents rows in a table, and I'm trying to get the row height to automatically adjust based on the max height of any of the labels inside the row.

The hierarchy is as follows:

Flexible Height Gallery (Table)
   Horizontal Container (Row)
      Vertical Container (Multiple lines in each row) 
         Horizontal Container  (Line 1) - Flexible Height Enabled
             Label 1
             Label 2
             ...
         Horizontal Container  (Line 2)- Flexible Height Enabled
             Label 5

It seems like the horizontal container that parents the labels can't adjust even thought it has flexible height enabled.

Is it an issue with how the horizontal container is configured, or an issue somewhere up the chain, such as one of the parent containers or the gallery.

Although it's weird, because a flexible height gallery still has a Template Size property which seems to fix each item's height in the gallery to a specific size, which I don't want.

On your horizonal container - you can set its Height property to:

Max(Label1.Height, Label2.Height, Label3.Height...) + Self.PaddingTop + Self.PaddingBottom
