almost definitely related to this issue of people running locally

Please confirm you have the latest versions of fastai, fastcore, and nbdev prior to reporting a bug (delete one): YES

Describe the bug
Image Cleaner will not scroll to the end of the images (it will barely scroll at all), because the scrollbar is so massive. I must zoom out a lot within my browser in order to see all the images

To Reproduce
ImageClassifierCleaner(learn)

Expected behavior
The scroll bar should allow one to scroll to the right

Error with full stack trace

I assume what is causing this is this line of code within vision widgets, maybe the hidden word is the problem?

def carousel(children=(), layout):
"A horizontally scrolling carousel"
def_layout = dict(*_*overflow='scroll hidden'_, flex_flow='row', display='flex')
res = Box([], layout=merge(def_layout, layout))
res.observe(_update_children, names='children')
res.children = children
return res
