Code Review
This pull request introduces a toggle method to the ExpansibleController, providing a convenient way to switch the expansion state. The implementation is clean and well-documented. The accompanying test correctly verifies the new functionality, though it contains a small amount of redundant code that could be removed for conciseness.

This test block is redundant. The toggle method's functionality is already verified by the preceding assertions that check the transition from collapsed to expanded and back.
As per the repository's style guide (line 11), tests should be concise. Removing this block will make the test more concise without losing any coverage.
References
- Line 11 of the repository style guide states that code should follow the guidance in the 'writing effective tests guide'. This guide emphasizes that tests should be concise and as short as possible. (link)
