[Bug][a11y]: Clear button isn't accessible

[michaelvalenti]

Bug description

Clear button is not a . It's a

element without any attributes to make it accessible.
To make it accessible we need to add role="button" and tabindex="0"

Expected behavior

It would be great if we can add role="button" and tabindex="0" to the clear button to make it accessible.

export type CBOptions = {
	className	?:string,
	title		?:string,
	html		?: (data:CBOptions) => string,
	role		?:string,
	tabindex	?:number
}

const options = Object.assign({
	className: 'clear-button',
	title: 'Clear All',
	role: 'button',
	tabindex: 0,
	html: (data:CBOptions) => {
		return `<div class="${data.className}" title="${data.title}" role="${data.role}" tabindex="${data.tabindex}">&#10799;</div>`;
	}
}, userOptions);

Steps to reproduce
