[ANGULAR] HorizontalScroll listener emits incorrect visibleDateRange

Hi,

The horizontalScroll listener emits widely far-off visibleDateRanges, either in the past or future when the viewPreset is changed.

I've attached a POC that changes the viewPreset to demonstrate this.

Also, a screenshot is attached showing a visibleDateRange jump of 2020 to 2000 to 2021.

We fetch data based off this date range and it's causing us to fetch an unnecessarily large amount of data.

You are missing infiniteScroll:true in your configuration. This option ensures that the visible range will be always reasonable (nobody would want to look at 100 years long timeline) and also that switching view presets will work as expected.

Hi Saki,

I tried enabling infiniteScroll to no avail. Issue still happens.
