The `autocapitalize="off"` attribute was added to the search and filter inputs in API docs with JDK-8320458. Although the `autocapitalize` attribute is defined in the HTML5 specification[1] it is not yet well-supported by tools such as HTML Tidy. Since these input fields are disabled by default and only enabled during page load, we could defer the setting of the `autocapitalize` attribute to the initialization script to avoid warnings/errors from these tools.
