Foliage painted onto a landscape will disappear when Sections per Component is changed from 1x1 to 2x2.

Affects 4.17.2 CL 3658906, 4.18.2 CL 3794801, 4.19 Main

Possible Workaround is to set the Resize Mode to Resample before applying changes

Steps to Reproduce
  1. Create new blank project, no starter content
  2. Create new landscape
  3. Use any mesh to create and paint foliage
  4. In Landscape Mode, under Manage, select Change Component Size Tool in the Landscape Editor Section
  5. Change Sections per Component from 1x1 section to 2x2 section and hit apply

Expected: Changes to Component Size applied, foliage not affected
Result: Changes to Component Size applied, foliage disappears
