In Firefox desktop with Kagi set as search engine, type a simple equation into the URL bar (e.g., "2+2").
EXPECTED: The dropdown of results includes the answer to the equation as the top line.
ACTUAL: There is no answer.
(I forget if you have to type "2+2=" or just "2+2" normally, but neither works now, so I can't verify what used to work.)
