Command + H won't hide Safari

Picking up on this thread... https://discussions.apple.com/thread/1347245

iMac 27-inch, Late 2012

macOS Catalina version 10.15.2

Still unable to hide Safari using the shortcut Command + H. Other programs appear to behave normally when using the shortcut and Safari is the only program with the issue.

I am guessing there is no solution out there and my Mac is getting older so I am sure Apple will stop supporting it soon. My work Mac is a lot newer and I am not experiencing the issue.

Who knows but frustrating all of the interesting quirks that Macs have these days. Not worth the premium price.
