Describe the Bug

I have defined a dynamic route [lang]/something/[[...dynamicParams]]/index.tsx and when I'm trying to redirect a user after submitting a form to an url like [:lang]/something/[...dynamicRouteParams]?searchParam=true (this is a representation of url, not an actual url). The important part here is an additional query param.

router.push('en/something/dynamicParam1/dynamicParam2?searchParam=true'); 

Unfortunately, after page reload an url in the browser address bar is showing: en/something/dynamicParam1/dynamicParam2?searchParam=true&lang=en&dynamicRouteParams=dynamicParam1&dynamicRouteParams=dynamicParam2.

Similar behaviour happens when using the next/link component.

Expected Behavior

I'm expecting an url as en/something/dynamicParam1/dynamicParam2?searchParam=true after page reload.

To Reproduce

router.push('en/something/dynamicParam1/dynamicParam2?searchParam=true');
