[MATCH HISTORY] Item purchase order missing for players who are disconnected at start of game (link)

Example: http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1726649154/203814846?tab=builds&participant=6

Sona was disconnected for the first part of the game. As a result, the "Item Purchase Order" section of her match history is blank even though she later reconnected and bought items.
