MARKLESS_STATE_PROPERTY_CLASS_INSTANCE

A class instance cannot be a field of a shared() or state() value: a Markless compiler error.

Error from the compiler, while it builds your .tsrx files.

What happened

Markless prints the message, the reason, and a suggestion:

MARKLESS_STATE_PROPERTY_CLASS_INSTANCE: A class instance cannot be a field of a shared() or state() value
Only declared graph fields cross the boundary. A class instance is not one, so the rebuilt object has a hole where the field was, and any method reached through the graph arrives unbound.
Make the durable data plain fields on the same object, and put the behaviour beside them as methods (`{ index: 0, next() { ... } }`).
