Adding #132597 as known issue for 8.19.0.

Placing it at the very bottom just to be consistent with other release notes in the 8-series (though known issues are better positioned towards the top of the release notes -- after breaking changes).

I think we can revert this PR, because the issue doesn't occur in 8.19. By accident I forgot the remove the feature flag that controlled whether the merge optimization was enabled. This has been fixed: #128459

Reverting change based on the [comment](#132683 (comment)).

Due to a PR CI issue, the [optimization](#125403) introduced in 8.19.0 that would have caused the [bug](#132597) didn't actually get enabled in 8.19.x versions.  Therefore, 8.19.0 and 8.19.1 do not have either the optimization or the bug.  The optimization will be enabled in 8.19.2 and the bug will be fixed by then.
