Suggestions on how to test this:

• The citation block should look and behave like it does in 5.10.
• Docs have been reverted to their previous state before the pull request was merged. No "Text" page under the Style Guide, for example. No release note about citation changes.

Does this PR introduce a user interface change? If mockups are available, please link/include them here:

Yes, the citation block should be back to its 5.10 state.

No.
