Copy + Paste Tempo Lines Causes Havoc in Orchestral Scores

[callumjohnspiller]

Issue type

Engraving bug (incorrect score rendering)

Description with steps to reproduce

1. Create a multi-bar tempo change line (will appear above woodwinds and strings)
2. Ctrl+C on a multi-bar selection (all filters off) underneath the tempo line (line will also be selected)
3. Ctrl+V on another line in the score
4. Observe that the tempo change line will appear above the pasted part
5. Also observe that if you Ctrl+V at the same point in time on another part, you will have multiple lines where there should only be one - further duplicates will be made above the string parts

Just through copy + pasting multiple bars I was able to produce this ungodly clarinet part - check out that second line!
