Context properties named in the ‘alternativeRestores’ property are restored to their value at the start of the first alternative in all subsequent alternatives.
Currently the default set restores ‘current meter’, ‘measure position’ and ‘chord changes’
Question: what aspects of chord changes revert?
I can't tell from the example what is being affected.
There is a chordChanges setting in the example,
but the output seems to be the same if you omit that.
What is the use case for this?
I could come up with a mwe if I knew what was intended.

\new Staff {

{ \chordmode { d:m } }
{ \chordmode { c:m } }

\chordmode { d:m }
