While I was writing a post on Busy.org, I found a bug as I entered the wrong spelling and went to correct it. As you write, mistakes can happen but it does not mean the whole writing content gets cleared. As a user, I would like to edit a character if something has been misspelled.
User should always be allowed to edit the tags for any spelling mistakes even if there is a mistake of single character. User should be allowed to go to the character, correct the spelling and come back to the end of the word to continue typing it to complete it without loosing the content.
As a user when you type the full tag and realize that the second or third character is incorrect in spelling, if you will go to the position of the misspelled character, edit to make it correct and come back to the end of the tag, the whole tag or word will disappear. User looses the whole word he typed before. Here the user should be allowed to continue typing to complete the tag.
To reproduce the issue, I have created a screen recording as well which can be found at the link: Screen Recording Link
