This has happened two times recently. I'm composing a new conversation post and suddenly the screen goes from left-to-right to right-to-left. Is there a control key to switch modes and I'm accidentally hitting it?
Never seen that before. Do you mean the text goes like this? Or something else?
A screenshot will be useful.
Also if you are able to inspect the editor content when it happens and provide the HTML, that'd be great. You just right click inside the editor, Inspect element, and then copy the contents of the fr-element fr-view element.
