steps to reproduce the bug
- click "edit" on Can anyone identify this object?
- try adding 1 tag (as an edit suggestion)
error message: "edits must be at least 6 characters" (red rectangle around composition window)
suspected source of the bug
My hunch is that the bug occurs when questions have the accidents or accident-investigation tags, because adding tags to all other questions works just fine, whereas theses tags trigger a yellow warning message.
When adding 1 tag as an edit suggestion for THIS QUESTION, I get the red rectangle ("at least 6 chars") around the composition box and the yellow warning text below the tags - related to the preexisting accident and accident-investigation tags.
For ALL OTHER QUESTIONS (without these tags) I can add 1 tag (and add zero characters to the question) as an edit suggestion without getting either one of these errors (i.e. no red red or yellow warning). I have done this many times. Therefore I suspect this to be the source of the bug.
