(core) Navigate hyperlinks in the same document without a page reload

Summary: Extract out function _onClickHyperlink

Test Plan: Made a table, formatted column as hyperlink, added values including a link to another page in the document, another document, and an external website, clicked on all the links and only the first one didn't open a new tab.
