Carries openchamber/openchamber#3124 until it lands: upstream commit
c82f188fc removed setActiveSurface from production code but left the
addSelectionToChat test asserting it, so the ui suite fails on any
branch including main. Byte-identical to that PR's fix; drop this
commit when rebasing onto main after #3124 merges.
