Runway length at LGW is OK for a 777.
I'd guess they knew it was safe and it's easier to deal with a plane full of pax at your originating airport than diverting to STN (where there's no BA ops) or LGW (BA have ops here so could have worked).

BA did fly from STN in 2017, at the time of the incident - they served short haul tourist routes like PMI, AGP, FLR, IBZ.
