This is limited by the current implementation of the auto-scroll gesture. It needs a refactor to determine scroll positions globally to get rid of the item mounting state.

这是受限于当前自动滚动手势的实现。需要重构以全局确定滚动位置，从而消除项目挂载状态。

感觉可以参考这个库的实现：drag_select_grid_view

该项目相较于参考的库而言复杂度不在同一个等级，需要调研层级调整对 delegate 整体交互效果的影响。
