Tabbing Into a Field That Opens a Chat Widget
3.2.1 — On Focus
Scenario
Setting
A recipe site's ingredient list
What’s wrong
Focus opening a chat widget that steals focus.
Example
Watch a recipe site's ingredient list closely and you'll spot this: focus opening a chat widget that steals focus.
Why it matters
Keyboard and screen-reader users, and people who are easily disoriented by surprise UI changes. Here, on a recipe site's ingredient list, the result is they have to relearn the layout on every page.
How to test
Tab to an element and stop: if a chat widget or other component opens and steals focus automatically, it fails.
How to fix
Receiving keyboard focus must cause no change — no activation, selection, navigation, popup, or focus jump.
Outcome
After the fix, the same visitor to a recipe site's ingredient list can now move confidently between pages.
Who is affected
Keyboard and screen-reader users, and people who are easily disoriented by surprise UI changes.
