Optimise Element.hasHoverStyle()

Open hrj opened this issue 10 years ago • 3 comments

Whenever mouse is hovered over an element, it and its descendants are invalidated.

This is extremely inefficient.

First round of optimisation is done.

More optimisations are possible:

  1. Cache the result of hasHoverStyle()
  2. Cache the boolean: descendant has hover styles.
