malikendsley/WT-16905 contains a fix that works but I'm not sure if its idiomatic. I'm also not very familiar with WT's testing workflow. There's also a test on that branch in src/mongo/db/storage/wiredtiger/wiredtiger_c_api_test.cpp (SpillLikeModifyThenSearchHang) that covers the issue. Without the provisional fix on that branch, that unit test hangs.
