@wiris/mathtype-ckeditor5 is not working after setting language

📝 Provide detailed reproduction steps (if any)

Take a lookout at this repository: https://github.com/7khatcode/Q2ACustomCkEditor.

I updated all packages to the latest version and set UI and content language to fa https://github.com/7khatcode/Q2ACustomCkEditor/blob/master/src/ckeditor.js

But when I use this editor the MathType and ChemType window is empty.

Error message :

Hi, thanks for the report and especially for the live demo. Unfortunately, I can confirm this issue. It seems to occur not only with RTL languages, but generally if you set language other than 'en'. I reported it in Wiris issue tracker, so you can follow it here: wiris/html-integrations#65
