Also not sure why Netlify is deploying in the first place (no docs changes) but it rebuilt just fine here, the PR check just isn't picking that up... |

This PR addresses a few outstanding
useLazyQueryissues and changes the behavior introduced in #10427 when a component unmounts before a query is fully resolved.Prior to #10427, components that unmounted before the query was resolved were stuck awaiting the promise indefinitely since promise resolution was dependent on the
useQueryrender cycle to resolve the promise. #10427 attempted to fix this by aborting the promise any time the component unmounted. This change however was a bit too spicy 🌶️ . Aborting the promise also made it impossible for some use cases that relied upon promise resolution to work correctly.This PR changes the behavior so that unmounting a component will no longer cause the promise to abort, but rather let the promise resolve naturally with the result from the server. This change had a number of positive side effects that resolved a number of other issues, for example, the ability to run the execution function multiple times with different variables in parallel will now resolve each of the promises with the correct data (#9755).
This PR also makes it possible to dynamically change the query document passed to
useLazyQueryand ensure the execute function will use the latest set document (#10198). Some additional tests were added to ensure rerendering with new variables before executing the query would use the proper option set.Checklist:
