Can you elaborate what you mean here?
If the mask expects the label to be modified, and the current value is
different from when it came in, we will apply the (flattened) changes.
If multiple ct() actions are executed in a single flow, none of them
should see the changes from the previous label change because they
should only appear after recirculation. (This isn't the case in this
version, but it will be in the next series I send out).
