It's following the temporary fix that was mentioned here #7381 (comment)

I tested this locally and it worked.

But I'm not sure what will happen if the text editor is mounted multiple times on a single page. The "global" variable is shared between all instances I think which will always return the same editor.

I wonder if we could go back to options api provide in the components that currently call provideEditor. It's what we used before and I think it should be possible to provide something in the options api that is returned from the setup function.

update: I pushed what i mean in #7628 - could you give it a try @st3iny ?
