Tags remove button submits forms they're contained by

[vcanales]

Bug report

• Package version(s): 1.4.0
• Browser and OS versions: Google Chrome Version 55.0.2883.95 (64-bit) on OSX el Capitan.

Steps to reproduce

1. Create multiple element within a form, with an onRemove event so that the remove button is rendered.
2. Click on the first tag

Actual behavior

onRemove is called but form is also submitted.

Expected behavior

only onRemove should be called, no form submits should occur (unless explicitly requested on the callback function)
