What is the current behavior? I’m getting error TypeError: fontFamily is undefined in theme.js:7993:11 file. It happens only in Firefox, no error in Chrome.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via fiddle.tinymce.com or similar. It happens on init of tinymce component. My init config is following:

tinymce.init({
            selector: 'textarea.mce.line-item-template',
            plugins: 'advlist autolink anchor code textcolor colorpicker contextmenu directionality hr image importcss template',
            toolbar: 'anchor code forecolor backcolor ltr rtl image template',            
            menubar: 'insert tools view format',
            contextmenu: 'link image inserttable | cell row column deletetable',
            contextmenu_never_use_native: false,
            forced_root_block: false,
            protect: [
                /\<\/?(td|tr)\>/g, 
                /\<\/?(td|tr) class=\"[\w\s-]+\"\>/g,
            ],
            verify_html: false
 });

What is the expected behavior? No errors in firefox.

Which versions of TinyMCE, and which browser / OS are affected by this issue? Did this work in previous versions of TinyMCE? Firefox Quantum 59.0.2 (64-bit) running on Windows, TinyMCE Version 4.7.11

Further testing shows the latest releases work with their recommended versions of Angular. That is: 5.0.8 and above is working with Angular 5 and 4.9.10 is working with Angular 4 (via @tinymce/tinymce-angular-legacy). I am closing this issue. If anyone can still reproduce this, please let us know.
