instead of using jQuery and loops, you can use XPath to get the element (and then check if it exists explicitly):
var unwantedSpan = document.evaluate( '//body/span[text()="BESbswy"]', document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null ).singleNodeValue
Or, if all you need is a Chrome browser, you can simply use
var unwantedSpan = $('//body/span[text()="BESbswy"]')
This range is only added on mobile devices and is performed using Google maps for calculation purposes.
