Make sure that these keywords have leading or trailing spaces and blank lines between them. e.g. keyword 1   keyword 2   keyword 3 Show all of the glossary entries. Expand one of the keywords select element. Confirm that all keywords are trimmed (no leading/trailing spaces) and no blank keywords are present. Click on a Keywords label. Confirm that the select element corresponding to that Keywords label gets focus. Check the page with axe DevTools or WAVE Confirm that there are no duplicate ID errors related to the Keywords select element.
