Release 0.8.2

We should create another release to fix #1621. I feel like quite a few people might run into that bug.

I also updated the devdependencies.

Publisher

• $ npm version has been run.
• Release notes in draft GitHub release are up to date
• Committer checklist is complete.
• Merge PR.
• Publish GitHub release using master with correct version number.
• $ npm publish has been run.
• Create draft GitHub release to prepare next release.

Note: If merges to master occur after submitting this PR and before running $ npm pubish you should be able to

1. pull from upstream/master (git pull upstream master) into the branch holding this version,
2. run $ npm run build to regenerate the min file, and
3. commit and push the updated changes.

Committer

In most cases, this should be someone different than the publisher.

• Version in package.json has been updated (see PUBLISHING.md).
• The marked.min.js has been updated.
• CI is green (no forced merge required).

I would prefer these dependency bumps in a separate PR.
