Crash on copy/paste with indent

[tonydroy]

I am not sure if copy/paste is supposed to preserve paragraph decorations in the current version (6/29/24). However, in the context of paragraph decorations, copy/paste either fails to preserve decorations or crashes.

I have attached a minimal file to exhibit the problem. CopyWithParDecTest opens the RTA with three short paragraphs: the first with neither spacing nor indent, the second with spacing but not indent, the third with indent but not spacing.

1. Copy and paste the first paragraph to the end: Everything is fine.
2. Copy and paste the second paragraph to the end: The paragraph spacing is gone.
3. Copy and paste the third paragraph to the end: CRASH!

For what it is worth, copying all three to the end does not result in an exception, but loses both spacing and indent.
