Hello Bokeh Team. The Slider values appear to increment by a factor of 2. I tested the rendering with Bokeh 2.1.1. on Chrome and Firefox. Here’s a sample:
from bokeh.models import Slider
from bokeh import io
slider = Slider(start=0, end=9, value=0, step=1, title="foo")
io.show(slider)
Moving the slider will display 2x increments of ‘value’. The example in Adding widgets — Bokeh 2.4.2 Documentation appears to show the same issue. Thanks!
