Dragcontrol in ios ,sometimes get a click reaction after dragend,why?d

there is a div for my 3js scene,when user click this div, i use raycast to see which mesh did he click,and create dragcontrol for this mesh
but sometimes at the end of the drag ,there can be unintentionally another click reaction ,usually select nothing,but will trigger my ‘havenoselect’ function.
it didn’t happen when i use my laptop to debug it,but will hanppen when i use the page in ios APP

Are you using a click event listener? If so, try pointerdown to see if this solves the issue.
