Lifecycle / Smart paste
Smart paste
People paste from spreadsheets, invoices, Slack and Word. What arrives is rarely what the field expects.

A paste that changes more than the value says so
Pasting +44… into a field set to US changes the country as well as the number. That is a bigger change than the user asked for, so the field shows what it did and offers an undo rather than silently rewriting the form.
