Datashade prevents framewise normalization

ALL software version info

holoviews: 1.14.1 bokeh: 2.2.3

Description of expected behavior and the observed behavior

Expected behavior I would expect the axes of the plot to update for every frame, even when a plot is datashaded.

Current behavior The axes do not update when a plot is datashaded. Notably, the exact same code below does work correctly if the datashade line is commented out.

Complete, minimal, self-contained example code that reproduces the issue

import numpy as np
import holoviews as hv
from holoviews.operation.datashader import datashade

hv.extension("bokeh")

x = [np.random.normal(loc=m, size=10_000) for m in [0, 1]]
y = np.random.normal(size=10_000)

plots = {c: hv.Scatter(zip(x[c], y)) for c in [0, 1]}

datashade(
hv.HoloMap(plots, kdims=["Component"]).opts(framewise=True, axiswise=True)
)

N.B.: Possible duplicate of #4396, but I wasn’t sure if it was the exact same. In any case this seemed like a more general version of the problem if it is indeed the same

This was previously fixed but all the fixes we introduced caused other regressions. I’ll dig up the relevant issues/PRs when I get a chance.

@bbradbury I think you should be able to use a panel HoloViews pane to display the dynamicmap and force an update by setting the object parameter when you need it to redraw. Hope that points you in the right direction!
