Description

When the list element has focus, Home and End moved the highlight and the browser also ran its native action, which scrolls the page or a scroll container to its top or bottom. The list's keydown handler from useListbox now prevents the native Home and End action. This applies to Select and Multiselect without a filter, embedded Multiselect and OptionList. With a filter, focus is in the input, and Home and End keep moving the text cursor.

From the OptionList accessibility review, question 2 (Home and End).

How has this been tested?

Unit tests in use-listbox.test.tsx: on the list, Home and End move the highlight and prevent the native action; through the filter input handler, they keep it. Unit tests for OptionList, Select, Multiselect, Autosuggest, Property filter and the shared list code pass, and eslint and tsc pass.
