Why do we need a test case for data-bs-toggle="dropdown" ?

[sijusamson]

In bootstrap documentation, it is clearly mentioned that we need to add data-bs-toggle="dropdown", no matter if we call via JavaScript or data-api, so why do we need a testcase in dropdown that it should add a listener on trigger which do not have data-bs-toggle="dropdown".
Adding screenshots of documentation and code for reference.

Test Case

The test ist needed for users they don't want to setup the bs dropdown automatically with the data-api.

The data-api data-bs-toggle="dropdown" is fine for users with static websites and users who serve the whole dom at once.
But for user who renders dynamically there html, need other ways to initialise the functionality. And for that people, is the test.
