fix(TrackNotes): 修復進度條節點消失問題

I found that the latest version of the player v8.30.1, the `addCues` API is not work, but the Biannual version (8.18.4) works fine.

If you change `cueType` from `custom` to `chapters` there should be no issue. Altenatively you can add to continue to use `custom`. You can see my example below:

```
timeSlider: {
  legacy: true
}
```
