Form submitted on input clear when geocoder is within form

[walter]

When the geocoder div is within a form and .geocoder-icon-close button clicked or user hits return after selecting a suggestion from keyboard, the form is submitted.

I confirmed this by taking the example code from here and adding a wrapping form around div.map and div.geocoder-container. Then I entered an address with suggestions and clicked the "x" (aka button.geocoder-icon-close). The form was submitted rather than simply clearing the input value.

I then also repeated the test, but instead of clicking the "x", I arrowed down to select a suggestion and clicked return. The form was also submitted.

This was in Safari, Chrome, and Firefox.

The mapbox-gl-geocoder is really handy! Thanks for all your great work. Just a little detail that would be great to fix or have insight about how to eliminate the behavior.
