The clear method is being called out of scope.
This is error occurring everytime we scroll in a TreeGrid with virtualization:
Uncaught TypeError: Cannot set properties of undefined (setting 'lastPos')
This seems to be the issue
export class TreeInterSectionObserver extends InterSectionObserver , but has no constructor and does not have the following
constructor() {
super();
}
In TypeScript when a class extends another class, the constructor of the base class "super' needs to be called or the inheriting class will not be created correctly. This is being done correctly in other classes in this file so it looks like an error of omission.
this is the constructor of InterSectionObserver
constructor(element: HTMLElement, options: InterSection, movableEle?: HTMLElement) {
this.element = element;
this.options = options;
this.movableEle = movableEle;
}
