Patches
- DetailsList has been modified to warn when "getKey" and "selection" props are passed simultaneously. The "getKey" property is never used if a Selection object is passed. Either the "getKey" prop from the Selection object is used, or Selection's default getKey implementation (item) => item.key is used, but never the "getKey" prop passed to DetailsList. Making "getKey" and "selection" mutually exclusive DetailsList properties prevents users from making this mistake. (PR #24048 by okonech)
