Japanese and Chinese text-align justify not working

[Irina]

Japanese/Chinese content is not justified.

Steps:

Type in some Chinese/Japanese characters.

Select the content and click 'Justify'.

Expected result: Text will be justified.

Actual result: Text is not justified, it is aligned left.

Can be reproduced in CKEditor 3.6.x and 4.x

If I remember correctly justify stretches the line of text. From editor perspective this is just adding style="text-align: justify;" to element like DIV or P. How browser is handling it other thing.

I have noticed it doesn't matter whether you use English or Chinese. Text is justified only when you have line of text longer then editor. Only then when you use Ctrl+A and justify style you get some movement.
It works the same in plain contenteditable element without CKEditor used.

@irina I'm closing this issue as invalid but if you don't agree please feel free to leave a comment.
