The current implementation does not support storing multiple sets of data (the key
parameter is mostly useless), which is fixed by this PR.
As a sidenote: The data storage indices for the keys are stored on the element attribute key
. HTMLElement does not use this attribute, yet, and to my knowledge no subtype does. But it is a very generic name which might be prone to collide in the future, maybe a more bootstrap specific attribute would be better.
