Uncaught TypeError: Illegal invocation

[wesleydeb]

Description

This is very similar to #357. We are also using a Froala editor in our Angular project. The issue is when a user clicks on the Wiris MathType or ChemType icon in the toolbar, there appear two Uncaught TypeError: Illegal invocation exceptions. After this point, clicking OK does not work anymore probably as a result of this. (We make a call to our own backend where we use the C# api to create an image of the input, but this function fails claiming the remote server returned a 403. After this we receive an Uncaught Error: Invalid string. Length must be a multiple of 4 exception on the client.) The editor window does however open correctly and everything in the editor still works.

Environment

Which version of MathType does this happen in?
"@wiris/mathtype-froala3": "^7.31.1"
but also tried:
"@wiris/mathtype-froala": "^8.4.0"
"@wiris/mathtype-froala3": "^7.26.1"
"@wiris/mathtype-froala3": "^7.27.1"

What is the relevant software and their versions?

• Editor: Froala ^4.0.8
• Framework: Angular ^14.2.0
• Browser: Edge 114
• Operating System: Windows 10

Steps to reproduce

1. [Setup the wiris plugin in the froala editor]

Expected result
