Do automatically updating search results count as a change of context?
Question
Answer
Under our interpretation of WCAG 2.1 AA, this would not be considered a change of context because of the content that is being updated; the "search results" for example within a listbox of options as a user is typing in the search field is not a major change that changes the meaning of the Web page.
However, if entering text into this search field does change any settings, then this would be considered a change of context.
Changes in context include things such as: opening a new window, moving focus elsewhere, going to a new page, and viewport changes.
