## Summary This PR fixes the alias redirect problem that was noted in the attached SDH. For context, as part of the [Links panel work](elastic#166896), I added [dashboard caching](elastic#162285) to make navigation more efficient - however, when implementing this, I did not consider the redirect behaviour. Specifically, we were **always** adding dashboards to the cache, even if the load outcome meant a redirect was necessary - so, because the meta info for the dashboard fetch result was cached, this meant that the `'aliasMatch'` outcome was **also** cached. Because of this, after a redirect happened, the second attempt to load the dashboard would return the result from the **cache** rather than fetching the dashboard from the CM client - but, as described previously, the cached dashboard would still appear as though it required a redirect because the cached outcome was `'aliasMatch'`. Therefore, because of hitting this early return on **both** fetch attempts (before the redirect, after the redirect)... https://github.com/elastic/kibana/blob/4565b1bfba91cd24f73f8ce37fa7be73283a4453/src/plugins/dashboard/public/dashboard_container/embeddable/create/create_dashboard.ts#L165-L171 ... the dashboard information would not get updated. _(Oof!)_ Despite the lengthy description of the problem, the solution is quite simple - just don't add dashboards to the cache if they require a redirect. And then everything works! 🎉 ### Videos **Before** https://github.com/elastic/kibana/assets/8698078/983b81a6-acf3-4e71-804a-6ed75c36896f **After** https://github.com/elastic/kibana/assets/8698078/028369ff-f73f-43e6-9abb-b35f0d2f33e1 ### Testing To test, I followed the directions from [this PR description](elastic#163658) to get a dashboard that requires a redirect - then, I created a markdown panel with the **old** (from the Default space) dashboard ID in the new space to see the same redirect behaviour that the customer in the SDH was seeing. ### Checklist - [x] This was checked for [cross-browser compatibility](https://www.elastic.co/support/matrix#matrix_browsers) - [x] [Unit or functional tests](https://www.elastic.co/guide/en/kibana/master/development-tests.html) were updated or added to match the most common scenarios ### For maintainers - [ ] This was checked for breaking API changes and was [labeled appropriately](https://www.elastic.co/guide/en/kibana/master/contributing.html#kibana-release-notes-process) (cherry picked from commit 27b34d5)
