Selecting ICA components in `ica.plot_components` doesn't work anymore

See original GitHub issue

If I click on the title of a component in the dialog produced by ica.plot_components(inst=raw), I get the following error:

  File "/usr/local/lib/python3.6/site-packages/matplotlib/cbook/__init__.py", line 389, in process
    proxy(*args, **kwargs)
  File "/usr/local/lib/python3.6/site-packages/matplotlib/cbook/__init__.py", line 227, in __call__
    return mtd(*args, **kwargs)
  File "/usr/local/lib/python3.6/site-packages/mne/viz/topomap.py", line 1006, in onclick
    label = event.inaxes.get_label()
AttributeError: 'NoneType' object has no attribute 'get_label'

Any idea why the label is gone and how to retrieve it (actually, event.inaxes is None)?

Ok, I’ll try to do it in one PR.

Did this change recently? AFAIR, you could click on the title and nothing happened.

I’m not sure, I never clicked the titles before. But I tried this on a previous matplotlib version and the error was printed in the console where I started jupyter notebook, but was absent in the notebook view. Maybe matplotlib changed something so now all the errors are passed to the notebook (that’s actually helpful).
