clickSelector only clicks first element found

[JelleBouwmans]

In clickAndHoverHelper.js the line await page.click(clickSelectorIndex); only clicks the first element found. It should click all elements found with the given selector.

Suggested fix:
for (var element of document.querySelectorAll(clickSelectorIndex)) { element.click(); }

This might also be the case for page.hover() and page.type() (keypress)
