Description
MWE:
from pathlib import Path
import matplotlib
import mne
matplotlib.use('Qt5Agg')
sample_dir = Path(mne.datasets.sample.data_path())
sample_fname = sample_dir / 'MEG' / 'sample' / 'sample_audvis_raw.fif'
raw = mne.io.read_raw_fif(sample_fname, preload=False)
raw.plot_sensors('3d')
Clicking on the frontal sensors reveals names of channels someplace else.

When show_names=True is passed, the channels are labeled correctly, though, leading me to believe that the odd behavior described above is related to click -> channel mapping
For completeness, here's a 2D sensor plot:
macOS with Qt5 backend.

Research direction
Run the provided MWE with the Qt5Agg backend and inspect viz.plot_sensors('3d'), comparing click-to-channel mapping with show_names=True and the 2D plot. Done means clicking a frontal sensor reveals that sensor's name at the correct location; the payload does not name a source file or test.
