Hi,

I’m having an issue when panning/zooming in a figure with circles when the X-axis is reversed (x_range=[1,0]) using Bokeh v2.2.3.

When panning/zooming, the circles dissapear when their boundaries touch the X-axis edge. When x is increasing (x_range=[0,1]), this does not happen.

I’ve deactivated the level of details downsampling option by precaution by it doesn’t seem related.

Any idea how to solve this ?

Here is a minimal working example:

```
from bokeh.plotting import *
import numpy as np
p = figure(plot_width=400, plot_height=400, x_range=[1,0],y_range=[0,1])
p.circle(np.linspace(0,1,num=500), y=np.random.random(500), radius=.03,alpha=0.1, radius_dimension='x', radius_units='data')
p.lod_threshold = None
show(p)
```
