The debian kicad package has now using the GTK3 flavour of wxwidgets3.0
for many months, so has this bug been solved (at least as far as kicad
and wxwidgets3.0 are concerned)?

If so, I think we can at least unassign this from wx and kicad.

If not, I'm very unclear what (as a maintainer of wxwidgets3.0) I'm
expected to do given that the problem clearly seem to lie lower down the
stack:
