Universal Editor - text alignment not working

In Universal Editor, when trying to align text in Rich Text field by using default alignment option (left, center, right), it only adds inline style. Upon saving changes and exiting out of RTE, all inline styles are removed.

I want to have per-paragraph alignment option within a rich text field so didn’t do this through custom model field. 

Any fix for this? Like adding a class instead of inline styling so this can actually work?
