Description
Hi,
I have been customising the hover template of a histogram, but it doesn't seem to recognise the name keyword when added to the template. Plotly version 5.10.0
import plotly.graph_objects as go
x = [1, 2, 2, 1, 2, 2, 3]
fig = go.Figure()
fig = fig.add_histogram(name='example', x=x, hovertemplate='%{name}')
fig.show()
The result (with hover):
What I should get: Same as above, but with %{name} replaced with example.

Research direction
Start with the supplied Python reproduction in issue #3864 and trace how histogram hovertemplate handles the %{name} token. Done means hovering the named histogram renders "example" instead of leaving the token unresolved.
