Editorial: Typos in deferred fetching quota section #1948

What is the issue with the Fetch Standard?

While reviewing the "Deferred fetching quota" section of the specification, I noticed a few minor typographical/grammatical issues:

1. Section 7.4: "...how much of their quota is delegates to cross-origin child documents..." -> should be "is delegated to".
2. Section 7.4 Example: "...because each frame reserve 8 kibibytes:" -> should be "each frame reserves".
3. Quota calculation note: "...decremented By quota reserved for deferred-fetch-minimal)" -> unnecessary capital 'B' and unmatched closing parenthesis.

I would be happy to submit a pull request fixing these.
