Editor problem rtl

hey guys, i have a problem with the new editor.
my forum is using the hebrew language which is RTL. at first the new editor starts with the ltr as default unlike the old one, plus after changing to rtl it makes in the post [rtl] before and after any sentences or the whole text and adding extra lines. also it makes the deleting hard to figure if you are deleting letters from the end of sentence or the beggining of it.

please fix it.
thank you.
