The method mounted on global in the ES Modules environment throws an error

[WoJiaoFuXiaoYun]

When I import litegraph.js in vite and encounter an error, I traced the code and found that the methods are mounted through global, while in the vite development environment, they are loaded using EMS.I think it should be this problem.

litegraph.js:16882  Uncaught ReferenceError: clamp is not defined
    at WidgetNumber.onMouseUp (litegraph.js:16882:12)
    at LGraphCanvas.processMouseUp (litegraph.js:6910:26)
