Copy/paste of two-bar repeat produces empty measures

Issue type

UX/Interaction bug (incorrect behaviour)

Bug description

When using copy/paste on a passage containing a two-bar repeat, the repeat is not copied.

Steps to reproduce

1. add a two-bar repeat to a score
2. select those two bars or any range containing them
3. copy
4. select a destination
5. paste

Result: the bars corresponding to the two-bar repeat as empty in the destination

Same for four-bar repeat.

Additional context

Same in 4.2.1 and 4.1.1; I can't easily test earlier MU4 releases. Not applicable to MU3 since there was no two-bar repeat.

I thought I remembered seeing an issue about this previously but am not finding it, open or closed. Since these elements also involve "no break" elements, it's no doubt a bit complicated to make this work. We could consider putting up a warning dialog, much as we do for "tuplet would cross barline" - but I'd recommending allowing the copy anyhow so the user can simply add back the repeats.
