There are some Code and Syntax Highlighting problems on this page

I couldn't solve but this page needs some interest.

There is a huge text dump on the following line while using firefox.

import { DataFormValidationMode } from 'nativescript-ui-dataform';

export default { template: <ActionItem text="Immediate" android.position="popup" @tap="onImmediateTap"> <ActionItem text="OnLostFocus" android.position="popup" @tap="onOnLostFocusTap"> <ActionItem text="Manual" android.position="popup" @tap="onManualTap"> <Button text="Validate manually" horizontalAlignment="stretch" @tap="onValidateTap()"> , data () { return { text: '', validationMode: DataFormValidationMode.Immediate, person: { username: '', password: '', }, personMetadata: { 'isReadOnly': false, 'propertyAnnotations': [ { 'name': 'username', 'displayName': 'Nick', 'index': 0, 'validators': [ { 'name': 'NonEmpty' }, { 'name': 'MaximumLength', 'params': { 'length': 10 } } ] }, { 'name': 'password', 'displayName': 'Password', 'index': 2, 'validators': [ { 'name': 'NonEmpty', } ] }, ] } }; }, methods: { onImmediateTap() { this.validationMode = DataFormValidationMode.Immediate; }, onOnLostFocusTap() { this.validationMode = DataFormValidationMode.OnLostFocus; }, onManualTap() { this.validationMode = DataFormValidationMode.Manual; }, onValidateTap() { this.$refs.dataform.validateAll() .then(result => { console.log(Validation result: ${result}); }); }, } };
