Re: [csswg-drafts] [css-values] Fallback value of ex height (#5243)

I'd derived that 0.8em figure a couple of years back, when I was still delving into font-metrics - I'd be a more specific about the platforms and fonts I tested with these days, not least because I now understand the variation across them! It's certainly based on the metrics tested on my Mac, and possibly not verified on other platforms.
