David T. Lewis uploaded a new version of Morphic to project The Trunk: http://source.squeak.org/trunk/Morphic-dtl.1396.mcz
==================== Summary ====================
Name: Morphic-dtl.1396 Author: dtl Time: 18 February 2018, 4:53:20.499469 pm UUID: 19d166b4-6992-40eb-b115-f0d605c9307b Ancestors: Morphic-dtl.1395
For world-in-world uses such as a Worldlet, displayWorld should act upon the outermost containing world morph. Restore this behavior by un-deprecating PasteUpMorph>>privateOuterDisplayWorld and updating its implementation to match the current PasteUpMorph>>displayWorld, then reverting to the original version of PasteUpMorph>>displayWorld, which sends privateOuterDisplayWorld to the outermost world morph (which usually is self).
