DynamicMap doesn't use Dimension's default value if the value is 0

[ruoyu0088]

Holoviews 1.13.3

Here is the code:

import holoviews as hv
hv.extension('bokeh')

def f(a, b):
    x = [0, 1]
    y = [a, b]
    return hv.Curve((x, y))

dm = hv.DynamicMap(f, kdims=[
    hv.Dimension('a', range=(-3.0, 3.0), default=0.0),
    hv.Dimension('b', range=(-3.0, 3.0), default=0.0)
])

dm

the output plot is:

the value of a and b is 0, but the y axis of the line is -3. It uses the start value of the Dimension's range.
