What version of Remix are you using?

1.0.6

What version of Node are you using? Minimum supported version is 14.

Steps to Reproduce

• routes/myform.tsx which is navigated like this http://localhost:3000/myform?returnUrl=/blog
• myform.tsx calls submit({values: ...}, {method: 'post'})
• myform.tsx action simply returns null
• URL now is missing the returnUrl=/blog query string

Expected Behavior

URL should remain unchanged and maintain its query string

Actual Behavior

URL only points to the plain route, without any query string
