Confluence search/find tool does not work as expected

When editing a page confluence overrides my browsers inbuilt search (control f) ability, however the implementation does not work as expected in that clicking 'next' after entering a search term does not take my browser to the occurrence of the term.
Steps to reproduce:
1. go to create a confluence page
2. on the create page screen enter text that fills your screen & then put the text 'findme' just on the next line so that it is not visible when you scroll up to the top of the page
3. then search for 'findme' it is highlighted.
4. observe that you are not taken to the 'findme' highlighted match.
