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.
