please read Kris' description again.
if you set ::tooltip-markup, ::has-tooltip is set automatically, and
you don't need to worry about it. this is *not* the case if you connect to
::query-tooltip and possibly return TRUE. there is no way for gtk to tell
this kind of setup and querying every widget would be excessively
expensive, so we need the user to set ::has-tooltip here.
