No Font Smoothing in Hello

I recently noticed that when switching from Astra to Hello theme that fonts appeared slightly thicker and less crisp. (This only applies to non-retina displays)

example

After some digging around it appears Hello is not applying font smoothing as per other themes. I tried this piece of CSS which seems to fix the issue.

/*font smoothing*/
body {
-webkit-font-smoothing: antialiased;
}
