/**
* Checks whether an Element is invisible for the end user.
*
* This is a combination of jQuery's :hidden selector (but with a slightly
* different semantic, see below) and a check for CSS visibility 'hidden'.
*
* Elements with display:contents have zero dimensions but their content
* is still visible, so they should not be considered hidden.
*
* Since jQuery 2.x, inline elements, such as span, might be considered 'visible'
* although they have zero dimensions (for example, an empty span). In jQuery 1.x, such
* elements had been treated as 'hidden'.
*
* As some UI5 controls rely on the old behavior, this method restores it.
*
* @param {Element} oElem Element to check the dimensions for
* @returns {boolean} Whether the Element either has only zero dimensions or has visibility:hidden (CSS)
* @alias module:sap/ui/dom/isHidden
* @since 1.72
* @private
