I see the components being copied in the Designer, but they formerly were accompanied by their event blocks in the Blocks Editor.
This no longer happens.
In this sample run, I
- created a blank Screen3, no components and no blocks
- switched back to Screen1,
- highlighted Screen1 in the components tree panel
- hit Ctrl-C
- switched back to Screen3
- highlighted Screen3 in the components tree panel
- hit Ctrl-V
- saw all the components pasted into Screen3
- switched to the Blocks Editor
- discovered a lone text block where there should have been event blocks copied over from Screen1.
