* This functions tells if the RxPlayer can trust on any browser data
* about video element visibility and size.
*
* On Firefox (version >= 67) :
* - The PIP feature exists but can be disabled by default according
* to the OS and the channel used for updating / getting Firefox binaries.
* - There is no API to know if the Picture-in-picture (PIP) is enabled
* - There is no API to get the width of the PIP window
*
* The element clientWidth tells the width of the original video element, and
* no PIP window API exists to determine its presence or width. Thus, there are
* no way to determine the real width of the video window, as we can't know when
* the PIP feature or window is enabled, and we can't have access to the windo
* size information.
*
* Moreover, when the document is considered as hidden (e.g. in case of hidden
* tab), as there is no way to know if the PIP feature or window is enabled,
* we can't know if the video window is visible or not.
* @returns {boolean}
