Jonas Jenwald af5789125f Try to remove the mozOpaque canvas-property (PR 6551 follow-up)
According to MDN, see https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/mozOpaque, the `mozOpaque` canvas-property is not only non-standard (obviously) but it's also been deprecated.
Instead it's recommended to use `alpha = false` when getting the canvas-context, see https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/getContext#contextattributes, which all of our affected code is already doing.
