Clicking "Cancel" on a comment in progress deletes the comment without requesting confirmation
Summary: Prevent accidental loss of comments due to hitting the "Cancel" button.
Currently, the "Cancel" button when typing a comment appears to immediately remove the textbox, removing any text that has already been typed. While this isn't entirely unexpected, it's easy to hit accidentally on mobile, and as such, either some kind of confirmation stage or restoration of the contents if it's reopened may save some user frustrations. Especially on a site that encourages long form discussion, the possibility of losing a comment with one tap could discourage users.
