Editor Lite: the vue component can not resolve standalone extension

The following discussion from !49237 (closed) should be addressed:

• @dmishunov started a discussion:

  note: In theory, one shouldn't need to explicitly call use when dealing with Editor Lite as a vue component — it does provide the extensions prop that can accept extensions. However, I've tried it here and it somehow I wasn't able to fetch the required extension. So I will resolve this thread in a follow up for myself to investigate and provide better support for extensions in the context of Vue applications
