The memoization changes [here](https://github.com/elastic/kibana/pull/212488/files#diff-b0cdd6dc57dd06dba69d90894de8c88a7bb7c71c0e58753f324eb8ba664a0782R18) to the plugin template wrapper, prevented 2 extra re-renders, but there is still an underlying problem of how the `PageTemplateWrapper` is used, as it causes unmounting and remounting of the security views when navigating between pages. The only other change was to rely on React's built in diffing on the alerts page for the page level filters (cherry picked from commit 7f32eb0) # Conflicts: # x-pack/plugins/security_solution/public/detections/pages/detection_engine/detection_engine.tsx
