Steps to reproduce

What is expected?

Console output should be false

What is actually happening?

Output true

const patchElement = ( n1: VNode, n2: VNode, parentComponent: ComponentInternalInstance | null, parentSuspense: SuspenseBoundary | null, isSVG: boolean, optimized: boolean ) => { const el = (n2.el = n1.el!) if (DEV || FEATURE_PROD_DEVTOOLS) { el.__vnode = n2 } ......

let a = {}
let b = a

expect(a === b).toBe(true)

When the component is updated,n1 is not equal to n2

You shouldn't rely on __vnode as it's internal

When the component is updated,n1 is not equal to n2
