instances of keepAlive child component are retained after HMR

[konpeki622]

Hello! I have a question, thank you for your time.

In vue3, if the child component of keep-alive was selected, it still shows old state on the devtools panel after I changed some data of the component. The reason is that new instance called mounted but the old instance of keep-alive components called deactivated without unmounted during HMR. I think that is designed correctly but it just triggered the event component:added without component: removed in devtools, which means the old instance was still stored in instanceMap and the old state was shown because the selectedId was not changed.

It took up space and make old state show as a consequence, so is it necessary to remove the old instance, or stay them here?
