Bug
It looks like properties() calls are binding to an old version of the method and not the latest version. properties() should always return the latest copy of the properties.
Package Version: 6.0.1
Code
https://codesandbox.io/s/dojo-codesandbox-template-0wfis
In this example, click on "Increment value", then "Click me"
Expected behavior:
The value "11" would be printed to the console (the latest properties)
Actual behavior:
The value "1" is printed to the console (the original properties)
