find-in-text selector does not seem to work when it's the last argument of a child selector

[ar7hur]

I don't know if it's a bug or if I missed something, but find-in-text selector does not seem to work when it's the last argument of a child selector:

(let [tree (-> "<div><div><span>a</span></div></div>" h/parse h/as-hickory)]
      (hs/select (hs/child 
                  (hs/tag :div)
                  (hs/find-in-text #"a"))
               tree)) ; => []

But it works when adding a dummy and:

(let [tree (-> "<div><div><span class=\"go\">a</span></div></div>" h/parse h/as-hickory)]
      (hs/select (hs/child 
                  (hs/tag :div)
                  (hs/and hs/any (hs/find-in-text #"a"))
               tree)) ; => works
