// If Blockly is compiled with ADVANCED_COMPILATION and/or loaded as a

// msg/js/*.js, which consists of lines like:
//
// Blockly.Msg["ADD_COMMENT"] = "Add Comment";
// Blockly.Msg["CLEAN_UP"] = "Clean up Blocks";

// Blockly.Msg module - so make sure it is, but only if there is not

// goog.exportPath_ (see closure/goog/base.js) invoked by
// declareLegacyNamespace only copies normal data properties, not
// accessors.  This can be removed once all remaining calls to
// declareLegacyNamspace have been removed.
//
// This is only needed in uncompiled mode (see
// google/blockly-samples#902); in compiled mode the exports object is
// already the value of globalThis['Blockly'].
//
// Note that this code will still attempt to redefine accessors on a
// previously-imported copy of the Blockly library if both are
// imported in uncompiled mode.  This will fail with TypeError as the
// accessors are nonconfigurable (which is good, as otherwise one
// accessors on one copy would call get/set functions on the other
