While working on translation of some article from English to Hebrew I noticed I get warnings due to AbuseFilter that matched my edit.

Debug info:
*I see in the background API request with action=cxsave, which saves a backup for the current work
*In the results cxsave.validations.mwWA.<SHORT ARTICLES> (יצירת ערכים קצרים מאוד)

This filter is defined more or less as follows: (article_namespace == 0) & (article_recent_contributors == "") & (new_size < 200)
I don't know why it does match to a WIP translation, which is much larger than 200 bytes (I guess AB sees new_size=0 since it isn't yet "saved").

I added to the AB filter action=="edit" as a workaround. (doesn't work)
