refresh data cause memory leak

[javahuang]

Expected behavior and actual behavior.

refresh same data cause memory become larger and larger

Steps to reproduce the problem.

Specifications like the version of the project, operating system, or hardware.

version: 0.25.4 operating system: chrome 88 macos

[javahuang]

self.dispose = function () {
...
if (self.observer && self.observer.disconnect) {
      self.observer.disconnect();
    }
}

after grid dispose, self.observer always return undefine, so MutationObserver can't disconnect

Memory leaks are caused by lingering references to data. This can be in the form of event listeners or functions that touched the data to alter order etc..

Using the heap inspector in chrome's performance dev tools can help shine a light on these refs. That's where I would start.
