file this as a ticket at : <a href="https://github.com/MapServer/MapServer/issues" rel="noreferrer" target="_blank">https://github.com/MapServer/MapServer/issues</a> <br>
(include your mapfile and commands, nothing about mapscript). I <br>
believe this is something to do with how inline features are handled, <br>
for labels, in KML output. (maybe related to the message <br>
"msINLINELayerOpen: Layer is already open!" that MapServer is yelling at <br>
us, ha)<br>
