There is an unavoidable space character being appended target element's `value` during the `text-expander-value` event: https://github.com/github/text-expander-element/blob/5b5f7ad1056327f1d297be8474fb689089115cb9/src/text-expander-element.ts#L128 Could this be removed or made optional? I think the consumer of the module should be in control of whether they want this space, or not.
