--- Comment #2 from Jimmy Thomsen <jimmy at codemagic.dk> ---
I can confirm this with Safari 13.1 (14609.1.20.111.8) on macOS 10.14.6 (18G4032), as well as with Safari on iOS (iPhone) 13.7.

Work around: Only execute OnStorage logic if document is not focused:

if (!document.hasFocus())
{
    // Execute OnStorage logic - tab does not have focus
}

Notice though that hasFocus() will return false in the active tab if Developer Tools is open and has focus.
