This is what the help text says about this issue

  $ hg help pick | grep 'active topic'
      The resulting changeset will have the current active topic. If there's no
      active topic set, the resulting changeset will also not have any topic.

wdir has no active topic: pick should clear topic of the resulting cset

  $ hg debug-topic-namespace --clear
  $ hg topic --clear
  $ hg pick 'desc("banana")'
  picking 2:fcda3d8dafd2 "banana"
  1 new orphan changesets
  $ hg log -r . -T '{rev}: {desc} ({fqbn})\n'
  4: banana (default)
  $ hg debug-topic-namespace
  none
  $ hg topic --current
  no active topic
  [1]

wdir has active topic: pick should use the active topic for the resulting cset

  $ hg debug-topic-namespace everything
  marked working directory as topic namespace: everything
  $ hg topic all-things
  marked working directory as topic: all-things
  $ hg pick 'desc("blackberry")'
  picking 3:48bbfbece8fa "blackberry"
  active topic 'all-things' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg log -r . -T '{rev}: {desc} ({fqbn})\n'
  5: blackberry (default//everything/all-things)
  $ hg debug-topic-namespace
  everything
  $ hg topic --current
  all-things

  $ hg log -GT '{rev}: {desc} ({fqbn})\n{join(extras, " ")}\n\n'
