Not sure if it's a bug, but that really affects many RTL boards when typing in English (or any other LTR language). I assume that the solution for that would be adding 2 more buttons to the editor LTR and RTL (can we do it only for RTL boards?). When on RTL style and trying to aligne to the left and write in English, it puts all the punctuation marks on the left side. In addition, the cursor stays on the left side all the time while typing. It affects the other side as well. LTR styles that type in RTL language(s), you can notice the same behavior. Thanks.
