Pre-configured page process element

Two issues re. using pre-configured pages.

I enabled debug mode using the browser console.  I then pressed Ctrl-F5 (cache reload) on an open process designer page, and tried to load the setup area of a pre-configured page element in the right hand panel.  It wouldn't load, the cursor just hung loading.  I then disabled debug mode and pressed Ctrl-F5 in the process designer window again.  The setup area of the pre-configured page element then loaded fine.

More problematic was the following while adding a button to run a process that opened a pre-configured page.  Using the debugger to step through a function that called the process with 'ProcessModuleUtilities', the configuration of the process call itself having a callback function for when the process had finished.  The debugger reported that the callback function was being called before the process had run and pre-configured page closed, not after.

define("ContactPageV2", ["ProcessModuleUtilities", "MaskHelper"], function(ProcessModuleUtilities, MaskHelper) {
	return {
		entitySchemaName: "Contact",
		attributes: {},
		modules: /**SCHEMA_MODULES*/{}/**SCHEMA_MODULES*/,
		details: /**SCHEMA_DETAILS*/{}/**SCHEMA_DETAILS*/,
		businessRules: /**SCHEMA_BUSINESS_RULES*/{}/**SCHEMA_BUSINESS_RULES*/,
		methods: {
			onProcessCallbackTestButtonClick: function () {
				debugger;
				const config = {
				    sysProcessName: "UsrPreconfiguredPage",
				    callback: function() {
				    	debugger;
				        Terrasoft.showInformation("The process has completed.");
				        MaskHelper.HideBodyMask();
				    },
				    scope: this
				};
				ProcessModuleUtilities.executeProcess(config);
			}
		},
