Hover tool disappears when flipping axis

[Jacob-Barhak]

It is nice having the default hover tool as support. However it disappears when flipping the axis of an image.

Below is code that will generate am html page showing proper behavior in one tab and the bug in another tab.

import numpy as np
import holoviews as hv
import panel as pn
from holoviews import opts
from bokeh.resources import INLINE
from holoviews.operation.datashader import rasterize
from matplotlib.cm import  PuBu

hv.extension('bokeh')
np.random.seed(1)
Matrix = np.random.random((1000,1000))

PlotData  = hv.Image(Matrix)  
ShadedBase = rasterize (PlotData, aggregator = 'max', interpolation = 'linear', dynamic  = False)
Shaded = ShadedBase.redim.label(x='X axis ',y='Time', z= 'Value' ).opts(cmap=PuBu, title = 'Working Well ' , xaxis='top', yaxis='left', height=1000, width=1000, tools=['hover'], toolbar = None, axiswise=True) 
ShadedFlipped = ShadedBase.redim.label(x='X axis ',y='Time', z= 'Value' ).opts(cmap=PuBu, title = 'Bug - No hover tool when Y axis is flipped' , invert_yaxis=True, xaxis='top', yaxis='left', height=1000, width=1000, tools=['hover'], toolbar = None, axiswise=True) 

out = pn.layout.Tabs( ( 'Hover tool Working Well',Shaded ),
                       ( 'Hover tool Not working with flipped axis', ShadedFlipped)
                      )

out.save('TestAxisFlip', resources=INLINE) 

I am using Python 3.7.4, holoviews 1.12.3 , Bokeh 1.3.4

Hopefully there is a simple fix.

This is a bokeh issue afaik, but I'll leave it open here for now.

Thanks Philipp, Can you elaborate, I am not sure how exactly it is redirected to Bokeh, so more details will be helpful. This is a minor issue since it only means that the plots will be flipped, yet if its a problem in Bokeh, is it worthwhile reporting it there? I'll be happy to do so using the same example. Jacob

Doesn't appear to be fixed.

This is working fine not on the development version:
holoviews version 1.13.0a22

Closing the issue.

[Jacob-Barhak]

To be exact, the versions that it works with are:
holoviews version 1.13.0a21.post10+gdf1a5803
bokeh version 1.4.0
