  • [data-test-id='prevent-default-key-events-secondary']

Fallback

  • section.prevent-default-key-events-container :nth-of-type(1)
  • .card.prevent_default_key_events button:nth-of-type(1)
  • form.prevent-default-key-events-form .field-group:nth-child(1)

Avoid

  • .mt-4.mb-2.flex.items-center > input:nth-child(1)
  • .css-1a2b3c4
  • div[class*='temp-'][class*='hover']
