Abstracts not expanding proberly when references are grouped by keywords (multiple keywords per ref)

Hello,

When the list of references are grouped by keywords, referecnes can show up multiple times in the list if thay have several keywords.

For example Bidule2014 will be listed under 3 different keywords and so will appear 3 times. Now if I try to expand the abstract of the 2nd or 3rd instance of Bidule2014 the abstract will not expand there and will expand under the first appearance of Bidule 2014.

It is a very minor issue, but maybe you did not know that it was behaving this way :-)

Cheers and thank you for your amazing work on Bibbase
