Foliage is disconnected from landscape when scultping in UE 5.8

Summary

The foliage is disconnected from the landscape in UE 5.8. If you paint new foliage then sculpt the landscape, the foliage doesn’t follow the landscape deformation.

To fix, you have to go to Project Settings > Engine > Landscape > Foliage Landscape Snapping Mode > Snap Under Brush Only.

Why is this the default behavior? This just completely breaks scultping landscapes with foliage from previous engine versions.
