Description of expected behavior and the observed behavior
I used to be able to combine whiskers into categorical plots using Bokeh 1.4.0. When I upgraded to 2.2.2, the whiskers disappeared. The plot I have in mind is a dotplot + whiskers + multi-category plot, with the (single) dot indicating the mean and whiskers as stderr.
Complete, minimal, self-contained example code that reproduces the issue
(this code is lightly edited from https://docs.bokeh.org/en/latest/docs/user_guide/annotations.html?highlight=whisker, and incorporates some categorical code (e.g. x_range=FactorRange(*x)) from https://docs.bokeh.org/en/latest/docs/user_guide/categorical.html.

When the code is run as provided above, this is what I got.
When the commented statements are uncommented (i.e. #base.append(str(year)) and #p = figure(plot_width=600, plot_height=300, title="Years vs mpg with Quartile Ranges")), and the line following that is commented out, I get
Not exactly sure what's wrong, but it seems to me that Whisker seem to only appear on numerical-type axis, not a factorial-type one? Thanks for looking into this!
