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.

Hmm, I tested this PR and when I tried to reproduce

#186642 (review)

Moving from an initial data view without timefield to one with timefield, on this instance
https://kertal-pr-200074-fix-histogram.kbndev.co/app/r/s/sWisD

I no longer had error message, which makes me consider if this could be already part of

#186642

WDYT? @jughosta ... however, due to the flaky nature of these problems, it could be the case that it just works/fails for me

[jughosta]

@kertal While it reduces the number of buildLensProps() calls, I now doubt that it can solve the recent issues.
