when i use micro-app(A micro front-end framework)，react-konva does not work normalcy。it only render a 。
this is example: containers：https://github.com/Lpbzzz/box konva: https://github.com/Lpbzzz/konva-demo According to the micro-app documentation, there may be some useful information： https://micro-zoe.github.io/micro-app/docs.html#/zh-cn/questions?id=_7%e3%80%81%e9%94%99%e8%af%af%e4%bf%a1%e6%81%af%ef%bc%9axxx-undefined
Reason:
In the sandboxed environment of a micro front-end, top-level variables do not leak to global variables.
For example, under normal circumstances, top-level variables defined via var name or function name () {} leak as global variables and are globally accessible via window.name or name.
However, in a sandboxed environment these top-level variables do not leak as global variables and window.name or name is undefined, causing problems.
