a work-around for VHints-scrolling issue on google docs
a work-around for VHints-scrolling issue on google docs

The page listens `scroll` event and hide the left sidebar,
but when VHints find scrollable items,
  some `scroll` events are made by Chrome...

Todo:
- suppress all scroll events in ~4ms after traverse ?
  - suppress all or only those on known "scrolled" elements?

New issue:
- is here a new performance regression?
