SimpleMDE seems to have several issues with Mantis and Browsers. Some of them are:
Middle-Click-Paste feature in Linux desktops doesn't work in the editor
Spell Check feature in web browser doesn't work. It doesn't indicate words with a typo
Height & Width cannot be changed per editor instance. This can be changed only in CSS and thus description, note, steps to reproduce, and additional information have the same editor size.
In some pages, SimpleMDE doesn't bug_change_status_page.php
Compatibility issues with dropzone. See more details at #6
