fixed backToTopButton hook

[Raj-Mandal-20]

Pre-flight checklist

• I have read the Contributing Guidelines on pull requests.
• If this is a code change: I have written unit tests and/or added dogfooding pages to fully verify the new behavior.
• If this is a new API or substantial change: the PR has an accompanying issue (the backtotopbutton only shows when scrolling up slightly after scrolling down #10135 ) and the maintainers have approved on my working plan.

Action Required

In order to merge any pull request (code, docs, etc.), we require contributors to sign our Contributor License Agreement, and we don't seem to have one on file for you.

Process

In order for us to review and merge your suggested changes, please sign at https://code.facebook.com/cla. If you are contributing on behalf of someone else (eg your employer), the individual CLA may not be sufficient and your employer may need to sign the corporate CLA.

Thanks for the PR

I'll turn it as a draft for now because we are still unsure of what we want to implement exactly.
