Disable Safari's "Email This Page" shortcut

I recently updated Safari to version 13.1 and discovered that the keyboard shortcut command-i now activates "Email This Page" in the share menu instead of italicizing text. My hatred of the Mail app and its constant intrusions aside, all I want is to be able to italicize text easily and efficiently the way my fingers have been accustomed to for twenty-odd years. Is there a way to turn this off or at least change the shortcut so I can have my italics back? I'm just about ready to scream.
