Re: [csswg-drafts] [css-values] Consider requiring same relative <length> units in atan2() (#8169) from Oriol Brufau via GitHub on 2022-12-02 (public-css-archive@w3.org from December 2022)

Also:

```css
line-height: 1ex;
font-weight: calc(1lh / 1px);
```

So, generalizing #2115, I guess the idea would be:

1. Compute `font-size`, resolving unknown font units with the parent. This sets the `em` unit.
2. Compute `font-weight`, resolving unknown font units with the parent. This sets the `ex`, `cap`, `ch` and `ic` units.
3. Compute `line-height`, resolving unknown font units with the parent. This sets the `lh` unit.

Or:

1. Compute `font-weight`, resolving unknown font units with the parent.
2. Compute `font-size`, resolving unknown font units with the parent. This sets the `em`, `ex`, `cap`, `ch` and `ic` units.
3. Compute `line-height`, resolving unknown font units with the parent. This sets the `lh` unit.
