Jira issue: CRDB-57079

The failure is in kv/kvserver.TestLogGrowthWhenRefreshingPendingCommands, with the reported assertion in client_raft_test.go. Start by reproducing the race-enabled test on release-25.4.0-rc and inspect the captured logs at outputs.zip/logTestLogGrowthWhenRefreshingPendingCommands4096739981. Done means the test no longer reports the wrong Raft leader in the shown lease and proposal case.
