While implementing my first version of inplace tips for the treeview,
I ran into the same limitation, The workaround I went with was
assigning to a (python) attribute on the cellrenderer: renderer.markup
= markup. Then when reading it (which was guaranteed to be for the one
cell in question), I would attempt to read the attribute off the
renderer. It required some explicit cooperation, but it's scads easier
(and probably better) than reimplementing the treeview from scratch.
