Using 'timeout' on listen_state causes "warnings" Loops - "Unexpected error in scheduler loop"

[bertonjit]

What happened?

Issue is very reproducible. Add a similar call as below in any app and then look at the main_log. The warnings appears every 1 sec while causes appdeamon to misfire on most automations.

This happens at the end of the timeout. As an example, if timeout is hour, the warnings start an hour after the below line is executed.

self.listen_state(self.Notifffy, "input_boolean.test_switch",new = "on",timeout = 10)

Version

4.5.13

Installation type
