Spinner Background Always Spinning

My spinners always seem to be spinning, but all-grey, when they are not active (value=False). It is perhaps more-visible when sized smaller. It is really obvious that it’s always spinning in the “top bar” of the dashboard. Wondering if this was actually introduced by more recent versions of Panel, because I don’t recall this in my early work on this project.

Here’s an MRE:

import panel as pn

spinner = pn.indicators.LoadingSpinner(value=False,
                                       width=30,
                                       height=30)

layout = pn.Column("some text",
                   spinner)

app = pn.template.MaterialTemplate(title='Test Dashboard')

app.main.append(layout)
app.servable()

pn.serve(app)

Is this the expected behavior?

I believe in Panel 1.4.0 it’ll be fixed
