Tremolo copy & paste results in wrong note types

For example: create a tremolo between notes using quarter notes. Copy the resulting tremolo to another place and notice the notes are displayed as quarter notes rather than the expected half note as in the original.

I'm going to add what I believe is another version of this. If you believe it's not the same problem, then I will create a new issue.

Note what happens when you copy the tremolos in this video

Notice the second dotted 1/2 note turns into an 8th tied to a 1/4 note.

I suspect it is the same, let's leave the issue as is but make sure when fixing we address both cases or else open a new one then.

Could you please attach the score from the gif? You can enter the same notes from scratch which is a workaround for now.

I didn't even bother saving the old score since it's so easy to reproduce every time, but here's another one I made in about 10 seconds. Copy measure 1 to another measure.

I'm suspecting this might have similar underlying cause as #280012: Crash opening vtest/tremolo-1.mscx. That crash happens on a layout that happens during read, there is no chord set for the tremolo yet. Perhaps the same basic problem leads to this issue as well. Also see #280095: Crash on part generation in the presence of tremolos
