For some reason, it was decided that web developers get to set the width of the Chrome scrollbar.
That's like allowing the petrol station to reset the width of my steering wheel.
I do not see a reason why users are expected to trawl the web for a fix and get lucky that the nth enigmatic recipe or extension works, or are advised to fiddle around with CSS code in order to restore a core functionality that should be set at OS level.
If I cannot trivially make it work, then lots of people won't either.
Ps.: How much user time is wasted on this 'feature'?
