state change in operator does not trigger an update

[SearleWork]

Followup to #483, sandbox updated

The problem is that state changes in operators do not trigger a re-render. If I use an action instead of an immediate assignment the re-render is triggered.

I set up this sandbox:

The code causing the problem is here:

on line 21.
