Data race when invoking services after shutdown

I am not sure if this is a problem or a feature, but invoking dependencies after shutdown creates a race condition (runnable code at https://goplay.tools/snippet/vIQ3Pwu4lw1):

package main

import (
    "log"
    "sync"
    "time"

    "github.com/samber/do"
)

type Service struct{}

func main() {
    var wg sync.WaitGroup

    i := do.New()

    do.Provide(i, func(injector *do.Injector) (*Service, error) {
        return &Service{}, nil
    })

    // uncommenting the line below gives an error: `Invoking after shutdown error: DI: could not find service `*main.Service`, available services:`
    //_ = do.MustInvoke[*Service](i)

    wg.Add(1)

    go func() {
        defer wg.Done()

        time.Sleep(time.Second * 1)

        _, err := do.Invoke[*Service](i)
        if err != nil {
            log.Printf("Invoking after shutdown error: %v\n", err)
            return
        }
    }()

    err := i.Shutdown()
    if err != nil {
        log.Printf("Shutdown error: %v\n", err)
    }

    wg.Wait()

    log.Println("Finished")
}

When running with go run -race . it detects a race condition:

Is this the intended way it supposed to work? Is the shutdown procedure expected to be a final call with no invoking of services after it?

I haven't dug deeply in the source code, but apparently the shutdown procedure does not operate under the write lock. Is there a particular reason for that?
