Arrow right jumps to start (possible bug)

I created the first two bars writing the normal way. The rest is done by repeating the two first bar using R.
When I navigate with the right arrow, focus jumps to the beginning instead of moving to the next object.
I guess it has to do with the copying of the first two bars. (it does so after each gliss in the second line).

Weird. It seems to be specifically the glissandi that are the problem. If you delete the glissandi and reinput them (and don’t copy and paste them) the arrow keys work fine.

I wouldn’t expect this to change any time soon: we will tackle this kind of problem when we come to tackle the wider issue of reworking arrow navigation, but that is not imminent.
