Flow stops when clicking Inject node

[colinl]

With the attached flow, the MQTT passthrough and 5 second automatic Inject work as expected.
However, if the Inject button is clicked the target machine stops (the MQTT passthrough stops).
Clicking Reconnect to xsbug springs it back into life.

Target is a Wemos D1 Mini configured as ESP8266, esp/nodemcu, running the plugin installed from github #0ee07c58f52a52f67ea138922036805eae751371.
