Bug Description

The following event listeners don't get cleaned up an could cause a potential memory leak:

wheel in packages/web-app-preview/src/components/Sources/MediaImage.vue
change in packages/web-pkg/src/services/uppy/uppyService.ts

Reproduction Steps

• add dev logs to track the registering and unregistering of those listeners
• open the preview app and close it
• open the "New"-menu and close it

Expected Outcome

The registered event listeners should be unregistered.

Actual Outcome

They stay registered.
