Add support for disabling top-scroll for partials

[Eason0729]

I have seen this issue: #1923

However, that issue seems to be about <form/> support.

I am working on load more button with <Partial mode="append">, more entries are loaded but client view keep scrolling to top.

Maybe I should just reopen that issue?

In my case, I wanted to stay on the same page andI was able to transform the link into a button without a form. Because of using the button element, it does not scroll to the top.

// before
<a href="/current" f-partial="/partials/content">Link</a>

// after
<button f-partial="/partials/content">Link</button>
