epi_page_context in TinyMCE

Hi, 

TL;DR: Is it possible to get the Episerver context in a custom TinyMCE plugin?

I'm trying to migrate a custom plugin in TinyMCE after upgrading to Episerver 11 and TinyMCE 2.8.0. 

The plugin uses epi_page_context which is available but empty in editor.settings after upgrading. In Episerver 10, SetPageDataContext could be used to set the context based on the supplied page https://world.episerver.com/documentation/Class-library/?documentId=cms/10/10AD80F5.

Are there any equivalent methods of getting the Episerver context in a custom TinyMCE plugin?
