three-full: Minified OBJLoader2 Async fails on building worker code

When OBJLoader2 is used async it builds the worker code by building up a string and passing it to the worker. Unfortunately some of the string is hard coded. That means that when it is minified (as all of my code is when I deploy) the strings aren’t the correct class/variable name any more.

In the following code you can see that LoaderSupport is hard-coded (eg. var LoaderSupport) but the Parser class definition has been minified, so where it should say LoaderSupport.Validator in prototype.setMaterials it says mh.Validator instead. I can’t think of a good way to handle this. Any ideas???

    var LoaderSupport = {};

    LoaderSupport.Validator = {
	    isValid: function(e){return null!==e&&void 0!==e},
	    verifyInput: function(e,t){return null===e||void 0===e?t:e},
    }

    Parser = (function () {

	function e(){this.callbackProgress=null,this.callbackMeshBuilder=null,this.contentRef=null,this.legacyMode=!1,this.materials={},this.useAsync=!1,this.materialPerSmoothingGroup=!1,this.useIndices=!1,this.disregardNormals=!1,this.vertices=[],this.colors=[],this.normals=[],this.uvs=[],this.rawMesh={objectName:"",groupName:"",activeMtlName:"",mtllibName:"",faceType:-1,subGroups:[],subGroupInUse:null,smoothingGroup:{splitMaterials:!1,normalized:-1,real:-1},counts:{doubleIndicesCount:0,faceCount:0,mtlCount:0,smoothingGroupCount:0}},this.inputObjectCount=1,this.outputObjectCount=1,this.globalCounts={vertices:0,faces:0,doubleIndicesCount:0,lineByte:0,currentByte:0,totalBytes:0},this.logging={enabled:!0,debug:!1}}

	e.prototype.resetRawMesh = function(){this.rawMesh.subGroups=[],this.rawMesh.subGroupInUse=null,this.rawMesh.smoothingGroup.normalized=-1,this.rawMesh.smoothingGroup.real=-1,this.pushSmoothingGroup(1),this.rawMesh.counts.doubleIndicesCount=0,this.rawMesh.counts.faceCount=0,this.rawMesh.counts.mtlCount=0,this.rawMesh.counts.smoothingGroupCount=0};

	e.prototype.setUseAsync = function(e){this.useAsync=e};

	e.prototype.setMaterialPerSmoothingGroup = function(e){this.materialPerSmoothingGroup=e};

	e.prototype.setUseIndices = function(e){this.useIndices=e};

	e.prototype.setDisregardNormals = function(e){this.disregardNormals=e};

	e.prototype.setMaterials = function(e){this.materials=mh.Validator.verifyInput(e,this.materials),this.materials=mh.Validator.verifyInput(this.materials,{})};

	e.prototype.setCallbackMeshBuilder = function(e){if(!mh.Validator.isValid(e))throw'Unable to run as no "MeshBuilder" callback is set.';this.callbackMeshBuilder=e};

	e.prototype.setCallbackProgress = function(e){this.callbackProgress=e};

And just for reference, here is the code that is causing the problem (the build worker code):

      var buildCode = function(funcBuildObject, funcBuildSingleton) {
            var workerCode = '';
            workerCode += '\n\n';
            workerCode += 'var LoaderSupport = {};\n\n';
            workerCode += funcBuildObject('LoaderSupport.Validator', Validator);
            workerCode += funcBuildSingleton('Parser', Parser);
            return workerCode;
      };
      this.workerSupport.validate(buildCode, 'Parser');
      this.workerSupport.setCallbacks(scopedOnMeshLoaded, scopedOnLoad);
      if (scope.terminateWorkerOnLoad) { this.workerSupport.setTerminateRequested(true); }

edit: add javascript tag to code
