supporting mixed RTL/LTR #1
Description
The editor does not support mixed RTL/LTR environments. languages like Persian, Arabic and Hebrew are written from Right-to-left. However, people who write in these languages usually need a mixed RTL/LTR environment as they may have LTR paragraphs (like quotes, code blocks, math equations, etc) along with their RTL texts. Therefore, each paragraph needs to have its own direction that can be set manually (like Google Docs) or automatically (like Dropbox Paper).
