Video is recording horizontal instead of vertical on mobile.

[Tschucki]

Description

I set the plugins.video.aspectRatio to 9/16, so it records a vertical video. This works well on desktop but not on mobile devices. There it records a horizontal video in portrait orientation.
What is strange, is that when rotating the phone to landscape it records a correct 9:16 video

Steps to reproduce

Set videoOptions:

videoOptions: {
                video: {
                    aspectRatio: {ideal: 9 / 16, min: 9 / 16, max: 1},
                    facingMode: 'user',
                },
                videoMimeType: 'video/webm;codecs=vp8',
                plugins: {
                    record: {
                        audio: true,
                        video: {
                            aspectRatio: {ideal: 9 / 16, min: 9 / 16, max: 1},
                            facingMode: "user"
                        },
                        maxLength: this.videoMaxLength,
                        videoMimeType: 'video/webm;codecs=vp8'
                    }
                }
            }
