 failed.

 Of course!

 [attachment:log_the_bug_unfiltered-3399.patch
 log_the_bug_unfiltered-3399.patch] allows for easy annotations of missing
 events in browsers.

 About logs:

  * "mouseout" and "safeOut" logs use {{{OpenLayers.Util.mouseLeft}}} to
 detect "Out"
  * "safeMove" use {{{Drag::mousemoveLeft}}} to detect "Out"

 The patch includes the adaptation of two examples:

  * "wfs-snap-split.html": Added the firebug.
  * "modify-feature.html": Added {{{styleMap}}} for square dots, this
 causes the failures are very frequent. Removed {{{Console.Log}}} on line
 44.


 Two examples of logs:

 1. Leaving the map by the top:

 {{{
 safeMove | Out: false x=97,y=87 | polygon id=""
 safeMove | Out: false x=97,y=77 | svg
 id="OpenLayers.Layer.Vector_48_svgRoot"
 mouseout | Out: false x=96,y=73 | polygon id=""
 mouseout | Out: false x=96,y=73 | polygon id=""
 mouseout | Out: false x=96,y=73 | polygon id=""
 safeOut | Out: false x=96,y=73 | polygon id=""
 safeMove | Out: false x=96,y=73 | polygon id=""
 safeMove | Out: true x=96,y=68 | DIV id="map"
 safeOut | Out: true x=95,y=66 | P id="shortdesc"
 safeMove | Out: true x=95,y=66 | P id="shortdesc"
 safeMove | Out: true x=95,y=64 | P id="shortdesc"
 safeMove | Out: true x=95,y=63 | P id="shortdesc"
 }}}

 2. Moving towards !PanZoom and moving to another button

 {{{
 safeOut | Out: false x=78,y=163 | polygon id=""
 safeMove | Out: false x=78,y=163 | polygon id=""
 safeMove | Out: false x=73,y=163 | svg
 id="OpenLayers.Layer.Vector_48_svgRoot"
 mouseout | Out: false x=69,y=163 | polygon id=""
 mouseout | Out: false x=69,y=163 | polygon id=""
 mouseout | Out: false x=69,y=163 | polygon id=""
 safeOut | Out: false x=69,y=163 | polygon id=""
 safeMove | Out: false x=69,y=163 | polygon id=""
 safeMove | Out: false x=63,y=163 | svg
 id="OpenLayers.Layer.Vector_48_svgRoot"
 safeMove | Out: false x=58,y=163 | svg
 id="OpenLayers.Layer.Vector_48_svgRoot"
 mouseout | Out: false x=56,y=164 | polygon id=""
 mouseout | Out: false x=56,y=164 | polygon id=""
 mouseout | Out: false x=56,y=164 | polygon id=""
 safeOut | Out: false x=56,y=164 | polygon id=""
 safeMove | Out: false x=56,y=164 | polygon id=""
 safeMove | Out: true x=52,y=165 | IMG
 id="OpenLayers.Control.PanZoom_2_zoomworld_innerImage"
 safeMove | Out: true x=50,y=166 | IMG
 id="OpenLayers.Control.PanZoom_2_zoomworld_innerImage"
 ... the same, 13 "safeMove" logs
 safeMove | Out: true x=40,y=171 | IMG
 id="OpenLayers.Control.PanZoom_2_zoomworld_innerImage"
 safeOut | Out: true x=41,y=172 | IMG
 id="OpenLayers.Control.PanZoom_2_zoomout_innerImage"
 safeMove | Out: true x=41,y=172 | IMG
 id="OpenLayers.Control.PanZoom_2_zoomout_innerImage"
 }}}

 These logs are obtained by using the example "wfs-snap-split.html" and
 using Chrome. Using Safari or FF quickly observed similar results, with
 either "wfs-snap-split.html" or "modify-feature.html" examples. [[BR]]
 For "modify-feature.html" with FF failures occur only sporadically, see
 ticket description.
