Describe the Bug

Using the { shallow: true } option with router.push previously prevented the browser from scrolling to the top of the page. I've tested versions 10.0.0, 10.0.1, 10.0.5 & the latest 10.0.6-canary.5 all of which have the bug. When using 9.5.5 and 9.5.6-canary.18 no scrolling happens which is the expected result.

Expected Behavior

No scrolling to top.

To Reproduce

Update a query string using router.push with the shallow option set to true. I'm using the example below for a "See More Results" button.

Using router.push('some-url?page=2', undefined, { shallow: true })

EDIT: Formatting

It's missing the current docs, but you can prevent this by passing { scroll: false } as the third parameter, e.g. router.push(url, as, { scroll: false }).

See #20606 for details.
