Repro for webkit

wkrev.com/150259 introduced a small regression where text decorations such as underlines are not repainted for whitespace text.

A user recently reported this against Chrome and I had merged the above patch a few years ago so we shared this bug. I fixed this by removing the whitespace check which keeps the original optimization but causes whitespace runs to be repainted. My fix landed in https://src.chromium.org/viewvc/blink?revision=202164&view=revision and a similar fix would work in WebKit too.
