Description of the problem

For some reason the procedure I've been using for years to plot multiple evokeds using plot_evoked_topo produces a misbehaving legend.

Steps to reproduce

import mne

path = str(mne.datasets.sample.data_path()) + '/MEG/sample/sample_audvis_raw.fif'
raw = mne.io.read_raw_fif(path)

events_1 = mne.find_events(raw)
epochs_1 = mne.Epochs(raw, events_1, event_id={'LH': 1})
evoked_1 = epochs_1.average()

events_2 = mne.find_events(raw)
epochs_2 = mne.Epochs(raw, events_2, event_id={'RH': 2})
evoked_2 = epochs_2.average()

mne.viz.plot_evoked_topo([evoked_1, evoked_2])

Expected results

Legend should have two lines that have matching colors to texts.
