MARKLESS_SHARED_SEED_UNSUPPORTED

Cannot seed shared state from this expression: 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_SHARED_SEED_UNSUPPORTED: Cannot seed "<target>" from "<target>" because a component body seeds a shared instance only from its own props or from constants.
A component body runs once during initial render. The compiler turns a shared-state assignment there into a per-instance initial value, which it can only build from values the render already has: this component's props and constants.
Assign a prop or a constant, or move the write into an event handler where the shared instance is already live.
