Describe the bug
Arising from https://support.microbit.org/helpdesk/tickets/86759 (private)

When playing a melody looping in the background, some are slower on the second and subsequent plays.

ode 16s then 22s,
wedding 8s then 8.5s

Other built in melodies don't seem to be affected.

It sounds like perhaps repeated notes are longer?

Go to https://makecode.microbit.org/_K818E6KF7eX1
Download to micro:bit V2
Open device serial console
Press button A
Wait for 2 plays
Hear longer notes on second play
See longer time in console
Press B to stop

Expected behavior
All plays are roughly the same length.
