Fyi I've opened #5823 which bundles several fixes to Baggage parsing including this issue, so we should hold on this PR for now. Also the changes in this PR aren't quite correct, we shouldn't be percent-encoding (or decoding) Baggage keys at all.

Hi @rxchitrx — just a friendly reminder that this pull request is waiting on you. The dashboard status comment has the open items and is kept current.

• Replying is enough to hand it off — answer, explain why no change is needed, or ask a follow-up. The dashboard routes it onward once nothing on the list is waiting on you.
• To hand it back for any other reason, including the dashboard getting this wrong, comment /dashboard route:reviewers.
