I published test article in CX2 production. It published without any issue but shows dirty markup.
See: https://gu.wikipedia.org/w/index.php?title=%E0%AA%A6%E0%AA%97%E0%AA%A1%E0%AB%80_%E0%AA%9A%E0%AA%BE%E0%AA%B2&type=revision&diff=577066&oldid=577065&diffmode=source
While adapting {{Coord|18.977129|N|72.829131|E|display=title}} template, CX2 shows it like:
```
<span id="coordinates">[[Geographic coordinate system|Coordinates]]: <span class="plainlinks nourlexpansion">[//tools.wmflabs.org/geohack/geohack.php?pagename=Dagdi_Chawl¶ms=18.977129_N_72.829131_E_ <span class="geo-nondefault"><span class="geo-dms" title="Maps, aerial photos, and other data for this location"><span class="latitude">18°58′38″N</span> <span class="longitude">72°49′45″E</span></span></span><span class="geo-multi-punct"> / </span><span class="geo-default"><span class="geo-dec" title="Maps, aerial photos, and other data for this location">18.977129°N 72.829131°E</span><span style="display:none"> / <span class="geo">18.977129; 72.829131</span></span></span>]</span></span>
```
This is same issue in CX1.
