I’m getting artifacts in my epoch plots when I mark an epoch as bad:

```python
raw = mne.io.read_raw(deriv_path)
events, event_id = mne.events_from_annotations(raw)
epo = mne.Epochs(raw, events, event_id, tmin=-0.5, tmax=1, baseline=(-0.3, 0))

mne.viz.set_browser_backend('qt')
epo.plot()

```

It seems to be a scaling issue because changing the epoch range with the up/down arrows resets the view to normal. I’ve been using mne for years and I think this first started with 1.10.

Here’s my sytem info: I’m using Ubuntu jammy on WSL2 on win11.
