Hi, I can't add any css class by inserting a file with the Insert/Edit file button. It works as expected if I use the Insert/Edit link button. JCE 2.8.5 Joomla 3.9.15 I've tried with firefox and chrome. Also, it may not be related to this issue, but when i click on the "classes" dropdown this error appears in the console:

downloadable font: download failed (font-family: "FontAwesome" style:normal weight:400 stretch:100 src index:0): status=2147746065 source: http://localhost/000/components/com_jce/editor/libraries/vendor/fonts/fontawesome-webfont.woff

Thank you.

The console error still appears, but the "classes" dropdown works now with JCE Pro 2.8.6 Beta 2.

Thank you much.
