I have a scatter plot involving a categorical axis in which I’d like to have some jitter to the categorical values. The `jitter`

function accomplishes this, providing the corresponding factor range as `range`

argument. But when I reorder the range (and axis), the jittered points don’t move along with it as I expected—they stay put. If this is the intended behavior, is there a straightforward way I can get the jittered values to move when the range changes? Below is a brief example where a button reverses a categorical axis: red jittered points move, blue jittered ones don’t. (Tested in 2.2.0, 2.2.3, 2.3.0dev8)

```
from bokeh.transform import jitter
from bokeh.models import ColumnDataSource, FactorRange, CustomJS
from bokeh.models.widgets import Button
from bokeh.layouts import column
from bokeh.plotting import figure
from bokeh.io import show
source = ColumnDataSource({
'name': ['a', 'a', 'a', 'a', 'a'],
'val': [1, 1, 1, 1, 1],
})
p = figure(x_range=FactorRange(factors=['a', 'b']),
y_range=(0, 2), plot_width=200, plot_height=200)
p.scatter(x=jitter('name', 0.5, range=p.x_range), y='val', size=5, alpha=0.5, color='blue', source=source)
p.scatter(x='name', y=jitter('val', 0.5), size=5, color='red', alpha=0.5, source=source)
button = Button(label='Reorder factors')
button.js_on_click(CustomJS(args={'x_range': p.x_range}, code="""
const factors = [...x_range.factors];
const reversed = factors.reverse();
x_range.factors = reversed;
"""))
column = column(button, p)
show(column)
```
