PR description

Checklist

Note that we require UI tests to ensure that the added feature will not be nixed by some future fix and that there is at least some test-as-documentation to indicate how the fix or enhancement is expected to behave.

• [ ] - Added Cypress UI tests
• [ ] - Ran npm test, ensuring linting passes and that Cypress UI tests keep coverage to at least the same percent (reflected in the coverage badge that should be updated after the tests run)
• [ ] - Added any user documentation. Though not required, this can be a big help both for future users and for the PR reviewer.

Please fix the style (standard) to pass the CI tests.
