Describe the bug
On the current master (i.e., after #7066) frontal EEG channels are drawn outside of the head in topoplots.
Steps to reproduce
The simplest variant is probably
mne.viz.plot_montage(mne.channels.make_standard_montage('standard_1020'))
Naturally it also occurs in plot_topomap and is particularly suboptimal for outline='head' and extrapolate='head'.
Expected results
I would expect the head circumference to intersect the positions of the outer AF, F, FT, ... PO, O electrodes. This would match previous behavior and common plots (e.g., the 10-05 paper http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.116.7379&rep=rep1&type=pdf or https://github.com/sappelhoff/eeg_positions).
Actual results
Hence, the head seems to be shifted vertically (T9 and T10 are also not vertically centered with respect to the ears).
Additionally, the comment in the extrapolation snippet https://mne.tools/dev/auto_examples/visualization/plot_evoked_topomap.html suggests that changing the sphere diameter has an influence, but it didn't result in any changes for me.
