Conversation
Object.values() returns a new array on each call, triggering unnecessary re-renders when used with useSelect. Use createSelector to memoize the result so it only changes when state.connectors does. Co-Authored-By: Claude Opus 4.6 <[email protected]>

Changes:
- Memoize
getConnectorsusingcreateSelectorso unchanged state returns the same array reference. - Add unit tests to verify referential stability and that updates produce a new reference.

This introduces any testing coverage for functionality that didn't exist before. Additionally, it checks whether the selectors return the same reference, which could regress over time. I don't feel strongly about these tests, but it really doesn't harm to have some basic verification in place, particularly knowing it was reported as a bug. |
