# Summary 

On iOS Safari 15.5, if a page sets `Cross-Origin-Opener-Policy: same-origin` and a user navigates back to the page via the back button, form elements on that page aren't correctly interactive. Demo site: https://safari-bug-andy26.vercel.app

# Details 

1. User is on a page without a COOP header (https://safari-bug-andy26.vercel.app)
2. User clicks a link to a page that sets COOP same-origin (https://safari-bug-andy26.vercel.app/api)
3. User submits a GET form with no action, or an action which is the same page - such that the same page is loaded with different query parameters. (https://safari-bug-andy26.vercel.app/api?select=day&search=)
4. User hits back button to return to the original form (https://safari-bug-andy26.vercel.app/api)
5. Form elements aren't correctly interactive. They can receive focus, but the keyboard isn't opened for text inputs, and the select box UI isn't shown for selects.
