I guess there is some confusion on what are the design goals of the Editor. Let me clarify that.
By design the EditorComponent is a What-You-See-Is-What-You-Get (WYSIWYG) editor - its content is visually consistent. To achieve this consistency some rules have to be applied and the underlying HTML may be modified. For example, for this particular case the <font> tag and some other tag attributes are not supported.
Having said that, we are planning to release a future update which will allow users to customize the behaviour of the Editor but since this would be a non-trivial task, I can't commit to a specific timeline.
I hope this helps. Please let me know if further clarification is needed.
Regards,
Petar
