[Infra] Container flyout state in Inventory

[jennypavlova]

Summary

After introducing the container flyout in inventory, the flyout state is not persisted after returning back from the details page:

• Steps to reproduce:
  • Open inventory, select Docker Containers in the "Show" drop-down and open a container flyout
  • Click on Open as page
  • Click on return Expected: The docker container flyout should be open and Docker Containers option should be selected Actual: Hosts option is selected and the flyout is closed

Implementation details

• "Show" drop-down: The state is persisted in the URL but the saved views are overriding the Docker Containers with the default Hosts option (nodeType param is used for the "Show" drop-down)
• There is a POC with XState that solves the issue: https://github.com/elastic/kibana/pull/176895/files
• The hosts flyout is working as expected because the hosts option is the default one:

• If a saved view with Docker Containers option selected is used the flyout for containers will be persisted when the user is back. Here we need to decide how to prefill the inventory options: Currently, the "Default" saved view will override the URL option if there is no saved view selected. One solution could be to have the URL options in case there is no saved view selected and overwrite only the default options - but that can override the saved view options we might want to persist (even in the "Default" option).

Solution ideas

The best solution will be to persist the show drop-down selection (Docker Containers in this case). It will require some investigation because of the way the saved views currently work.

A possible workaround will be to not persist the flyout state when the user is back to the Inventory page (only in case of inventory - the hosts page should work as expected)

I think this is a good option.

Are there other open bugs about the inventory not keeping its state when navigating in and out? I found https://github.com/elastic/kibana/issues/85122, which looks like it's about saved views specifically, but if there weren't these bugs in the inventory, everything would be behaving as designed.

Moving this out of ECO and Ready to the maintenance backlog. We're ok with the current state of things for the moment, and can fix the navigation problem with the inventory in the future.
