[csswg-drafts] Pull Request: 🐛 FIX: Typos & Grammar

ahmadawais has just submitted a new pull request for https://github.com/w3c/csswg-drafts:

== 🐛 FIX: Typos & Grammar ==
Fixes a couple of typos and grammatical errors like:

- [x] `editting` to `editing`
- [x] `Nesting allow` to `Nesting allows`

```diff
-	some people find the nesting difficult to visually distinguish
+	some people find the nesting challenging to distinguish visually
```
Looking forward, peace! ✌️
