Collapse with multiple target stopped working in 5.3.0

Describe the issue

Until v5.2.3, the collapse plugin allowed a button to control several targets.
e.g. data-bs-target="#hello,#world"

Since v.5.3.0, it only appears to work with a single selector. With multiple selectors, there are no errors, but no collapsing

I did read https://getbootstrap.com/docs/5.3/migration/ to see if this was an intentional change.

Thanks for reporting this issue @fisharebest.
On my side, I don't have all the history in mind for this component so I don't know if this was something really supported voluntarily or not. The JS team will add more information later on.
In the meantime, the following could probably help you to have a workaround based on the multiple targets documentation where a common class is used as an example: https://codepen.io/julien-deramond/pen/RwqedgY
