[meghanmurphy1]

Summary

As part of Accessibility requirements, a user thats using only the keyboard should be able to know which element they are on at the moment after closing windows. As part of that the 'Ingest Pipelines' page, the 'Manage' button now refocuses once the 'Delete Custom Pipeline' popup is closed. See screenshots below

Closes #196650

Looking at the issue shouldn't we also focus on an element when we complete the delete action?

Expected Result

Focus should be on Manage button.
After pressing Enter on Delete pipeline, it would be better to have focus on the first element on the page (for this page probably Pipelines tab would be better).

why do we need to use the setTimeout here?

[meghanmurphy1]

From what I've read, the action closeDeleteModal re-renders and without the setTimeout the refocus will fail since the DOM hadn't updated yet.

Ahhh yes must have missed this. I think I can just add another button refrence for the Pipelines Tab.
