Fix flaky select test by adding timing delay

The CreatableOption test was failing because it was trying to find the
listbox role immediately after clicking the select, but the dropdown
needs a moment to render. Added a 100ms delay to ensure the dropdown
is fully rendered before looking for the listbox element.

This resolves the failing test in the CI pipeline.
