Pop-up menu is not dismissed when clicking "Edit"

When you click the three-dots menu in the Action column of a titles list, a two-item menu pops up, "Edit" and "Ignore".

When you click "Ignore", the pop-up menu disappears as expected, but when to you click "Edit" and the title-chooser pops up, it does not: it remains on the page along with the KB title-chooser popup.
