User Interface Software
WebUI, FluidDial
What happened?
I configured the the homing_button_pin and it works fine to perform the homing. But the after_homing macro is not executed on button push. When using the FluidDial or the WebUI to perform homing the macro is executed after it's homed.

PR #1489 might fix it. I don't have time to set up a test at the moment.
