fix: Inject context into onUserInput calls

[FrederikBolding]

Inject context into onUserInput requests, this reduces complexity on the client-side where the UI system no longer has to keep context up to date. Also fixes a problem where we weren't keeping the context properly up to date.

Fixes #3069
