Strange bug, home button animation.

[frederickdawg]

I basically have my home button not set for Google assistant, yet everytime I tap the home button to close out a screen I get that Google circles animation occuring.
I managed to get rid of this behavior by re-enabling Google app as I had it disabled before.
It appears that disabling the Google app is what triggers the home button animations, regardless of having Google assistant off . Bug or feature?
