"Copy PK" does not work in Safari

[PaulRBerg]

Current Behavior

In Safari, on both desktop and mobile, the burner private key is not copied in clipboard when going to "Advanced" and then tapping "Copy PK".

Expected Behavior

The burner private key should be copied in clipboard.

Environment

I used sablier.burnerfactory.com in Brave, Chrome and Firefox, and the "Copy PK" button worked. In Safari, on desktop and mobile, it did not.

• iPhone XR (iOS 12.3.1)
• Macbook Pro (macOS 10.14.6)

Looks like Safari handles copying differently than other browsers, all copying functions should be updated to support iOS.
