Wrap widgets broken

[rand5]

Previous solution to wrap widgets is no longer functional:

display("text/html", "<style>.cell .widget-area .widget-subarea { flex-direction: row; flex-wrap: wrap; }</style>")

I assume this is related to changes made in ipywidgets 7.0: "Widgets are now displayed in the output area in the classic notebook and are treated as any other output."
Is there a potential workaround? I've played with injecting other bits of html via display("text/html",...) but no luck as the widgets don't seem to be readily editable.

It seems like one way to address this is via hbox:

S1 = slider(1:1:10)
T = repmat([S1],10)
hbox(T...)

but the sliders are auto-sized to fit in a single line. If you know a priori how many sliders you want you could break it up using two calls to hbox:

S1 = slider(1:1:10)
T1 = repmat([S1],5)
T2 = repmat([S1],4)
display(hbox(T1...))
display(hbox(T2...))

But this seems sub-optimal
