Video preview image in the progress bar displayed incorrectly in split-view mode

[YiranDuan721]

Describe the bug
In split-view mode, if the camera view is adjusted to a smaller percentage, the video preview image in the progress bar will be displayed incorrectly, possibly due to its size calculated incorrectly.

To Reproduce
Steps to reproduce the behavior:

1. Go to any VoD with both presentation and camera views
2. Switch to split-view mode
3. Adjust the horizontal gutter, so that the width of camera view is relatively small (approx. less than 500 pixels from my attempts)
4. Hover over the progress bar, to see that the preview image is displayed incorrectly
5. Continue to adjust the dividing gutter a little to the right
6. Hover over the progress bar, to see that the preview image is displayed incorrectly with more images in vertical orientation
