FastApiIntegration not obeying failed_request_status_codes

[magroski]

How do you use Sentry?

Sentry Saas (sentry.io)

Version

2.33.0

Steps to Reproduce

sentry_sdk.init(
    dsn=os.getenv("SENTRY_DSN"),
    environment=APP_ENV,
    release=APP_VERSION,
    send_default_pii=True,
    integrations=[
        FastApiIntegration(
            failed_request_status_codes={*range(400, 600)}
        )
    ]
)

app = FastAPI(
    title="My Api",
    version=APP_VERSION,
)

@app.get("/sentry-debug")
async def trigger_error():
    raise HTTPException(status_code=403, detail="Forbidden cannot be updated")

This is not sending errors in the 400-500 range to Sentry, even though the parameter is {*range(400, 600)}. I also tried {403, *range(400, 600)}, but the error does not get sent.

However, if I change status_code to anything in the 500-600 range, it works

Expected Result

I expected to see 4xx errors on Sentry after setting the option failed_request_status_codes as described on the documentation here: https://docs.sentry.io/platforms/python/integrations/fastapi/#options

Actual Result

But for 403, nothing new on Sentry:
