Summary

Fixes #115209

To reproduce this bug it is required to have many documents (> 1M documents should work - use the makelogs in case) and create a Lens visualization with the Percentile function. It may be required to refresh a couple of times to see the error, as Elasticsearch, in some circumstances, returns an empty object.

This is a similar issue as the one fixed in #113216, but affecting single percentile.
Tests have been provided.

Risk Matrix

Delete this section if it is not applicable to this PR.

Before closing this PR, invite QA, stakeholders, and other developers to identify risks that should be tested prior to the change/feature release.

When forming the risk matrix, consider some of the following examples and how they may potentially impact the change:

Risk Probability Severity Mitigation/Notes
Multiple Spaces—unexpected behavior in non-default Kibana Space. Low High Integration tests will verify that all features are still supported in non-default Kibana Space and when user switches between spaces.
Multiple nodes—Elasticsearch polling might have race conditions when multiple Kibana nodes are polling for the same tasks. High Low Tasks are idempotent, so executing them multiple times will not result in logical error, but will degrade performance. To test for this case we add plenty of unit tests around this logic and document manual testing procedure.
Code should gracefully handle cases when feature X or plugin Y are disabled. Medium High Unit tests will verify that any feature flag or plugin combination still results in our service operational.
