script widgets not always refreshing correctly

Describe the bug
I have a "master" script widget and with two or three "slave" script widgets. The master widget checks on a few things and writes information into BTT variables, which the slave widgets then read to update their contents.

If I set the slave widgets to never run the script themselves, but only run it when the master widget issues a refresh_widget on them, then they do not update correctly (if I run the script from the configuration window, then it returns the correct string).

If I set the slave widgets to a, say, 5-second run schedule, then they update correctly. I'd rather not do this, as I'm trying to cut down on "polling" scripts. The reason I do it this way is so that I can have a single script that runs to a schedule and all other scripts are run only when needed.

Conclusion: It would appear that refresh_widget is not running the associated script.
