Steps to reproduce: Start GeoServer with release profile on localhost port 8080. (Not essential to the bug, just convenient to show its expression.) Go to [this map](http://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=Img_Sample,topp%3Astates&bbox=-1.3885038382960921E7%2C2870337.130793682%2C-7455049.489182421%2C6338174.0557576185&width=768&height=414&srs=MapML%3AOSMTILE&styles=&format=text%2Fhtml%3B%20subtype%3Dmapml) Open the layer control for the layer settings. Un-check the imagery layer \<map-extent> Check the imagery layer \<map-extent> What should happen: The imagery layer \<map-extent> should draw underneath the vector (states) layer. What actually happens: The imagery layer \<map-extent> draws on top of the vector (states) layer.
