Surveys question re-ordering is confusing

[liyiy]

Bug description

Please describe.
If this affects the front-end, screenshots would be of great help.

If you have a survey with multiple questions and you switch around the order of the questions post launch, the responses become mixed together and difficult to parse. We don't track ID on the questions so there's no concept of a stored state of order

If you are on PostHog Cloud it would be really valuable if you can share any links where the problem occurs. This speeds up our ability to troubleshoot tremendously.
