Severe delay occurs when dragging files or folders in the file list #488
Description
你好！我真的很喜欢你的Border主题，但是我在文件列表拖拽文件或文件夹时遇到了严重的延时问题。
Hello! I really like your Border theme, but I'm experiencing significant lag issues when dragging files or folders in the file list.
一开始我是想使用Manual Sorting插件对文件夹排序，但是当我拖拽文件夹时，出现了问题。
At first, I wanted to use the Manual Sorting plugin to sort the folders, but I ran into a problem when I dragged the folders.
如图所示，如果我们单击文件夹不放并且稍微拖动一点，鼠标旁边就会出现一个黑色的小框，一直跟着鼠标。（由于我在截屏所以没有鼠标）
As shown in the picture, if we click on a folder and hold it while slightly dragging it, a small black box will appear next to the mouse and follow it. (There is no mouse in the screenshot because I was capturing the screen)
但是接下来，当我把文件夹用正常速度拖动到我的目标位置时，这个黑色小框却还停留在原地，然后用乌龟般的速度一点一点的过来，并且还伴随着掉帧。
But then, when I drag the folder to my target location at normal speed, this little black box still stays in place, then moves over very slowly like a turtle, accompanied by frame drops.
