fix(html): style (CSS) content appears in HTML text (#2132) 
Fixes #1958.

`<style>` is invalid where it appears in the HTML of thw WSJ page
mentioned by that issue but invalid has little meaning in the HTML world
if Chrome accepts it.

In any case, we have no use for the contents of a `<style>` tag wherever
it appears so safe enough for us to just strip all those tags. Note we
do not want to also strip the *tail text* which can contain text we're
interested in.
