sortation is broken. For example... searched for radio>all receivers, filtered for ACCST protocol.. results show 36 possible RXs, first 2 top of the list is the
Top:     "FrSky V8FR-II 2.4Ghz 8CH Receiver (HV)" at £20.24
Second: "Turnigy TGY-iA6B V2 Receiver 6CH 2.4G AFHDS 2A Telemetry Receiver w/SBUS" @ £9.08

Then, toggling any of the sortation options - relevance, lo price, hi price,newest - those 2 remain at the top.. no sortation is being done.

Also, the third result is:
OrangeRx GA800HV Futaba FASST Compatible 8ch 2.4Ghz Receiver 

and the fourth:
Turnigy iA6 Receiver 6CH 2.4G AFHDS 2A Receiver 

... neither of which are ACCST protocol, so the ACCST filter argument is being ignored too.

Tested and same results on MS Int Expl and MS Edge
