DOM attributes aren't refetched during el.removeData().data()

[rbut]

When calling .removeData() and subsequently .data() one would expect from the documentation that the result of .data() would contain the current data-* attributes from the DOM.

Instead the result of .data() is an empty dictionary!

I have a JSfiddle showing the issue:

The workaround for now is to call the following on each element after .removeData() and before .data():

jQuery._data(this, "parsedAttrs", false);

It seems the private parsedAttrs data isn't being cleared in removeData().

Thank you.

I've updated the fiddle and included the workaround to show the fix:
