/**

* property for Qt browsers on Windows to hidden, thus fixing the following
|
|
* problem:
|
|
* Some browsers don't have full support of the object-fit property for the
|
|
* video element and when we set video object-fit to "cover" the video
|
|
* actually overflows the boundaries of its container, so it's important
|
|
* to indicate that the "overflow" should be hidden.
|
|
*
|
|
* Setting this property for all browsers will result in broken audio levels,
|
|
* which makes this a temporary solution, before reworking audio levels.
