How can I free the memory of scratch

[Hydrostic]

Expected Behavior

Actual Behavior

I have a project written by Vue that embedded the scratch player. I found that when the page jumps, even if I unmount component using ReactDOM.unmountComponentAtNode() in advance, the memory of the scratch is still used, and the memory will become larger every time I reopen it. Finally, the page will crash. How can I free the memory of scratch?
