Two-finger scroll zoom not working correctly in Qt6

[astrofrog]

If I run the following in IPython:

from pywwt.qt import WWTQtClient
%gui qt
wwt = WWTQtClient()
wwt.set_view('Earth')

with PyQt 6.6 installed on MacOS X, if I try and zoom in/out with two-finger scroll, the zooming is erratic and sometimes goes in the opposite direction to the way it should go.
