Description

See jsfiddle at http://jsfiddle.net/d5w4jpxq/71/ :

<input name="hashtags" type="tags" pattern="^#" placeholder="#hashtags">

Still allows data that doesn't start with a hash to be entered. The docs mention HTML5 pattern support - should we use pattern to limit the input or should we do this via change events?

Contributor guide

Research direction
Investigate the pattern attribute implementation in the tags input component to understand why it doesn't prevent invalid input. Look at the source code handling of the pattern attribute and any event listeners that validate input.
