Research direction
Start with the linked CodeSandbox and reproduce the failure in Firefox 136.0.4, comparing the first clean load with subsequent loads across the reported Angular and TinyMCE versions. Done means the editor initializes reliably on repeated loads in Firefox without the reported promise TypeError, while preserving the working Chrome behavior.
Written by the indexing model from the issue text.
Description
What is the current behavior?
TinyMCE fails to initialize in Firefox with the following error:
Uncaught (in promise) TypeError: t is undefined
On Chrome there's no such issue for the same page.
It is strange though, that the error doesn't show on the first clean load (in a private window) and the editor initializes correctly. But on second and consequent loads, it doesn't work and shows the error in console.
Please provide the steps to reproduce and if possible a minimal demo of the problem via codesandbox.io or similar.
What is the expected behavior?
Which versions of TinyMCE/TinyMCE-Angular, and which browser / OS are affected by this issue? Did this work in previous versions of TinyMCE or TinyMCE-Angular?
tinymce-angular^8.0.1
Angular^19.1.2
Firefox 136.0.4 (64-bit)
Tested on Windows 10, Linux, MacOS
