Kibana version:
main

Describe the bug:
After a refactoring the isLoading property is always set to false and it never turns to true.
This was working properly, after the various refactorings this got commented out and stopped working.

https://github.com/elastic/kibana/blob/main/x-pack/platform/plugins/shared/lens/public/editor_frame_service/editor_frame/config_panel/esql_editor.tsx#L313

The problem is that the cancel doesnt work now and there is no UI confirmation for a long running query

Expected behavior:
isLoading flag should correctly be set to the editor
