Use `<Plug>(easymotion-s)` in multiple buffers in IdeaVim?

Hi,

I use the easymotion plugin in IdeaVim with my PhpStorm.
Is it possible to use the `<Plug>(easymotion-s)` functionality in over multiple buffers in PhpStorm?

If I set a overwin mapping and use it, in PhpStorm it will creates only a new line and pastes `verwin-<letter-of-mapping>`.
