refactor(scrollView): only update DOM on changes
refactor(scrollView): only update DOM on changes

On line 1188 and 1094, only make updates to the content element’s
transform style when there are actual DOM changes that need to be made,
instead of accessing the DOM just to set the same value. Also many
style() updates.
