After I submit text for the flagging reason “In need of moderator intervention”, it's not possible to edit it.
So my feature-request is: after submitting the "In need of moderator intervention" flag, allow me to edit my text for that flagging reason any number of times before the flag is reviewed by a moderator.
I can edit my spelling mistakes, and add more information for that flagged question.
This is just like suggesting edits. I can make changes to my suggested edit any number of times before it gets reviewed. E.g. I can correct a typo error that I introduced.
