Why the doc says background-color is faster than backgroundColor?

[LongTengDao]

Unlike React's style attribute, Solid uses element.style.setProperty under the hood. This means you need to use the lower-case, dash-separated version of property names instead of the JavaScript camel-cased version, such as "background-color" rather than backgroundColor. This actually leads to better performance and consistency with SSR output.

Hello, I'm a new mvvm engine author.

In my simple test, style['backgroundColor']='red' and style['background-color']='red' is always faster than style.setProperty('background-color','red') in Chrome / Safari / Firefox / Edge.

Whay solidjs choose .setProperty under the hood, which expect better performance? Thanks!
