I happened to notice while stepping through the StackUnwindingWin64 test that it never actually encounters a runtime-compiled function despite using %OptimizeFunctionOnNextCall. V8 compiles the function on the subsequent call as requested, but the compiled function isn't very good because there was no feedback data, and it immediately deopts. To fix, we can call the function once between %PrepareFunctionForOptimization and %OptimizeFunctionOnNextCall.
