Regression in Panel or Bokeh; overpopulated tabs don't show arrow anymore

Haven't dug too deep, so not sure if it's a bokeh or panel issue.

import panel as pn
pn.extension()

pn.Tabs(*[(str(i), i) for i in range(100)], height=200, width=200, scroll=True)

@mattpap Did this change in Bokeh at some point?

[mattpap]

If we are talking about scroll arrows then it's a regression since 3.0 and new layout.

Yup scroll arrows. That's quite unfortunate, although I'm surprised this flew under the radar until now.
