Note that this project is released with a Contributor Code of Conduct. By participating in this project you agree to abide by its terms. Contributor Code of Conduct.

• [x] There is no existing PR that addresses this problem
• [x] Mentioned any existing issues in your commit so they get linked and closed once this PR gets merged, i.e: Closes #1554 in the body of a commit
• [x] Followed the instructions in the Contributing document
• [x] Ran the unit/spec tests and ensured they still pass
• [x] Added tests to cover the new behaviour
• [x] Updated the documentation to match the changes
• [ ] When possible, add an entry to the CHANGELOG file
• [ ] Squashed your PR down to a single commit. You may forego this if the PR tries to address multiple issues. Though we prefer one PR per feature/fix, sometimes that's not feasible. In that case ensure that a single feature/fix and associated tests and documentation is bundled up in one commit

Optional, but extra points:

• [x] Added tests to ensure the old behaviour cannot accidentally be reintroduced
