When services are added to ArcGIS Experience Builder via the portal, a feature selected using the Select widget results in intermittent zoom-out behaviors.
This is not a bug. When selecting features, it first zooms to the bounding rectangle of the selected features. However, due to the large volume of layer and feature data, the highlight effect takes a short while to render. At this point, the zoom-to operation has already completed and navigated to the specified extent, but the highlights are not fully displayed yet, thus creating the false impression that the zoom extent is incorrect. Additionally, some polygons are multi-part. When users select only a portion of a polygon visually, it actually selects all its parts. This mismatch between visual perception and actual selection also contributes to the same visual illusion.
解决办法
Add or select any one of the layers in the Select widget.
