I'm curious how the 2nd resize doesn't cause the scrollbar to go away

What I think happens: We are doing the resize in a onScroll event. We resize, notice it made scrollbars visible and resize again. Scrollbars are hidden in the end of this scroll event. And I suppose browsers won't fire another scroll until the previous is done.
And throttled() prevents multiple onScroll's in same frame.

Initially I was storing the width, but accidentally found out, it was not really needed.

Ahh, that's a good find. If throttled() can prevent the double event then I'm ok with testing this out further
