Bug when pasting to an ossia?

I found a strange phenomenon when pasting the contents of a normal piano staff to an ossia staff.

In the last 2 pages of the attached file I wanted to copy the contents of the normal staves to the ossia and then modify them, but for some reason I can’t do it for the left hand content of bar 200. I select the notes, copy them, and when I try to paste them to the ossia, they’re pasted over the original staff instead (with duplicated noteheads)

I suspect the problem is to do with the presence of the pedal line, which really does have to be attached to the bottom staff. If you deselect the pedal line before copying the music will paste correctly into the ossia staff.

Hadn’t thought of that, thanks!
