 * Bug 1864564 - Override esri._css.names containing -moz-prefixed css rules names
 * Webcompat issue #129144 - https://github.com/webcompat/web-bugs/issues/129144
 *
 * Esri library is applying -moz-transform to maps built with it, based on UA detection.
 * Since support for -moz-transform has been removed in
 * https://bugzilla.mozilla.org/show_bug.cgi?id=1855763, this results
 * in maps partially or incorrectly displayed. Overriding  esri._css.names
 * containing -moz-prefixed css properties to their unprefixed versions
 * fixes the issues.
