Summary Web Inspector: DOM Tree broken if an element has a "debounce" attribute

Summary: DOM Tree broken if an element has a "debounce" attribute Test: <body><div debounce="debounceUpdate"></div></body> Steps to Reproduce: 1. Inspect reduction 2. Show Elements tree => <body> doesn't have expected <div> child. Notes: * Error in Inspector: [Error] TypeError: Attempted to assign to readonly property. _addAttribute — Main.js:9238 _setAttributesPayload — Main.js:9180 DOMNode — Main.js:8681 _setChildrenPayload — Main.js:9212 Evaluating: this._attributesMap[name] = attr; Where name is "debounce". This is hitting Object.prototype.debounce which is not writable. We should avoid these issues by making attributesMap an actually `Map` and not an Object.
