Single item array query parameter not correctly parsed in Azure App Services in 5.2.1

When we deploy our app on Azure App Services, a single query parameter is not parsed when using the `?param[]=value` notation. Express will show this as a query param with the name `param[]` and the value `value`, while locally we get the correct behaviour: `param` and value `[value] ` ## Environment information **Version**: 5.2.1 **Platform**: Linux Azure App Services **Node.js version**: 24 **Any other relevant information**: Issue only occurs when running on Azure App Services. When running locally, it works as expected **This issue started for us after upgrading to the 5.2.1 version.** We had no issues when running the 4.18.x version ## What steps will reproduce the bug? Add a debug endpoint, e.g.; ```Typescript router.get("/debug/query", (req: Request, res: Response) => { const rawQueryString = req.originalUrl.split("?")[1] ?? ""; return res.json({ parsedQuery: req.query, rawQuery: { queryString: rawQueryString, }, }); }); ``` Send a request with the query format `?param[]=value`.
