Wavesurfer scroll resets to 0 when using the setOptions method with splitChannels

[MikeSegal]

Hi,
I am working on a project where I want to display a single channel from a URL.
When doing my research, I found that the easiest way to achieve this is to create a wavesurfer instance with the splitChannels option, and to set the height of the unwanted channel to 0.

This works for the most part, however when zooming in and setting the scroll to a specific time, and then calling the setOptions method, the scroll resets back to 0.

I saw that this was mentioned in an earlier issue (3189) and solved, however I managed to recreate this in this example

I wasn't sure if this is worthy of opening an issue, so I decided to post this here.
Thanks for any help!
