Safari only: Avia-Search clicked to open causes page to reload

Hey Enfold-Team,
during cross-browser testing I stumbled upon a problem with the avia search (avia-search-tooltip, the interactive ajax search). Works fine in all browsers but Safari – if I click on the search symbol, it causes the page to reload (and the url in the browser bar to add “/?s=” on the already opened url), no chance to write something in it. Somehow it seems to be interpreting the opening click already as submit click. For my page see link in private content.

Would be great if you can help me sort this out!
Thanks in advance,
Joerka
