Go submits the task unwrapped, so unlike the Submit and TrySubmit variants it never checks the pool context. A Go task still queued when the context is canceled runs anyway and counts as successful, not canceled. The README says drained tasks "are not executed".

a2e34e8 (v2.7.0) moved the context check from readTask to wrapTask. Before it, a queued Go task did not run after cancellation. Go never used wrapTask (pool.go#L333-L335), so it lost the check.

Wrap the task with wrapTask and the pool context, as wrapAndSubmit does. The callback is a no-op because Go has no future. The test mirrors TestPoolStopAndWaitShouldNotDeadlockWhenContextCanceledWithQueuedTasks.

Validation (Go 1.27.0):

• The new test fails on 52d2178 in 3 of 3 runs with -race and passes with the fix in 50 of 50.
• go test -race ./..., go vet ./... and git diff --check are clean.
• Go makes one more allocation per call (2 instead of 1); Submit makes 7.
