Hello,

is is there a way to get the mouse hover to follow the actual location when doing a contourf plot? At the moment it jumps around if I just do a very basic example. I have been looking at the help for `hv.help(hv.Polygons)`

but did not seem to find anything.

Here is a minimal example:

```
import holoviews as hv
import numpy as np
import xarray as xr
import hvplot.xarray
hv.extension('bokeh')
test_array = xr.DataArray(np.random.rand(460,500) + np.linspace(0,3,500),
coords=[np.arange(460), np.arange(500)],
dims=['x','y'], name='z')
test_array.hvplot.contourf()
```
