Comment:

 The original report appears to cover two seperate issues. As @dd32
 suggests, the 403 errors are likely a broken install.

 The uncaught promises are the result of a TinyMCE bug fixed by a
 [https://github.com/tinymce/tinymce/commit/d1877933fa1e98430e5e9e1f78884be60766d2f0
 recent commit on the TinyMCE repo]. It was fixed in TinyMCE 4.7.0

 I've been able to reliably reproduce it under the following conditions on
 the WP 4.9 branch:

 * multiple instances of `wp_editor()` are ''correctly'' called on the edit
 screen
 * TinyMCE is not cached by the browser and a scroll event is triggered
 before it loads

 @azaozz @iseulde would you consider bumping/hacking TinyMCE for WP 4.9.2?
