Observed: As of the latest Protopie version, when scaling up a container using the pinch gesture, child layers that have constraints all set to fix width and height and constraints on all sides are toggled off, would erratically repostion. The X position of child layers would scale relatively, but the Y position would all default to 0, being stuck to the top. This to me indicates that relative position for the Y of child layers are broken.
Expectation: In previous Protopie versions, when pinching and scaling up a container that has child layers within, the child layer would reposition relative to the scale. This is very useful for prototyping maps with location pins, as the pins would reposition when a user pinches and zooms in the map (Illustrated in the first screenshot).
