Improve responsive in adjoint layout for Bokeh backend #6527
Description
First observed in #6511. The main plot would fill more than what it currently does:
import panel as pn
import holoviews as hv
hv.extension("bokeh")
main_plot = hv.Curve([]).opts(responsive=True)
adj1_plot = hv.Curve([]).opts(width=80, responsive=True)
adj2_plot = hv.Curve([]).opts(height=80, responsive=True)
plot = main_plot << adj1_plot << adj2_plot
pn.panel(plot).servable()
