I have written a drag-and-drop component, which registers various events as shown in the following figure. The width and height of li are both 100% of the width and height given.

the following error occasionally occurs when dragging, but it will not affect normal use? What is the general situation of this kind of error?

[Intervention] Ignored attempt to cancel a touchstart event with cancelable=false, for example because scrolling is in progress and cannot be interrupted.

the null event that adds touchstart to the parent element to block the default behavior does not change the error report.
