Hi,

with bokeh 2.3.2 under jupyter I have a problem when the slider is vertical.  
Here the piece of code which reproduced my problem

```auto
import bokeh
from bokeh.io import show, output_notebook
from bokeh.models.widgets import DateSlider
from datetime import date
slider = DateSlider(start=date(2021, 1, 1), end=date(2021, 6, 17),
                    value=date(2021, 5, 17), step=1, title="Stuff",orientation='vertical')
show(slider)

```

As you can see cursor can’t be used (no problem when slider is horizontal).

Any idea ? 😳  
By advance thank you  
(It was working perfectly until yesterday when I ‘pip install panel’ for treemap purpose [Treemap chart - #3 by \_jm](https://discourse.bokeh.org/t/treemap-chart/7907/3) but not sure it is correlated )

@odadoun

I can reproduce the behavior in your example with bokeh 2.3.x (x=0/1/2/) in an environment that doesn’t have panel installed.

It looks as if this is a known bug being tracked in the bokeh GitHub Issues. See [Vertical sliders’ appearance is broken #10444](https://github.com/bokeh/bokeh/issues/10444).

The discussion in that issue also proposes a workaround until the bug is directly addressed.

The change in behavior could be **correlated** to changes to your environment as you suggest depending on which version of panel you pip-installed and any dependency it has on a minimum bokeh version (such that bokeh was also updated as part of the procedure). But the problem here is a regression in bokeh.

ok thank you. I think in the meanwhile I use the horizontal version …

Can add that I also ran into this a few versions of bokeh ago, but it has since been fixed.
