Thread:Project:Support desk/Whether edit filters do count preview actions

Hi,

Please refer to this hit to a filter on mr wikipedia. During regular examination of past hits I came across this hit. I am bit intrigued with this hit since the user does not seem to have clicked save button, if he had clicked save button, then there was nothing to stop change to take effect. I would like to understand whether edit filters may hit during just a preview action ? or is there any other possibility which might have stopped this edit to take effect ? Whether this hit is a regular expected behaviour of edit filter or it is a bug in itself ?

If hits are given on user preview actions then, whether those preview actions are counted in a edit filter where rate limit is mentioned ? Just I am trying to find if such edit filter behaviour is becoming cause of false positives. Actually I want to reproduce T100638 bug, which I have experienced once in a while but uptil  now I have not been able to reproduce.
