Not merging this in. Need to wait for filter feature change in Trace Details #10742 to merge in. I will then pull these changes locally to rebase and fix any conflicts before pushing.

[yanatha99]

Some tests failing from mix of index pattern and data fetch errors due to 500s. Seems like they just flaked? Need a re-run to be 100% sure no problems with change.

Just a reminder: DO NOT merge this PR. Merge #10745 instead.
