[Observium] search MAC in FDB

Hi,

trying to use the search option in observium.

If i go to FDB Tables and pick a random MAC-Address and enter it in the searchfield there is no result.

Whereas when i do this with any other search-option (ipv4;MAC Address;ARP/NDP) and enter appropriately, there is an result.

Tested with 0.13.8.4262 and 0.13.7.4172.

Has anybody a solution for this?
