I found that it would automatically scroll several times the first time

I obtained the data list through the backend interface, and when binding the card swiper, I found that it would automatically scroll several times the first time before stopping at the index position. This is why and how to avoid this problem, so that it should not automatically scroll a few times and directly locate at the index position the first time

when loop = true;

This is the log of index changes that I output，
Finally locate at index=2

I also encountered continuous scrolling when loading for the first time,
I load the component by checking if the data source is empty
hope to help you

When the data is empty, this problem occurs. My solution is to not display the component when the data is empty. Once the data is obtained, the component can be displayed. You can use a ternary expression to check this.
