• Target version: main

Summary

The form for changing the board color and name has 2 buttons, one to cancel the changes and one to save them. Because both buttons are of native-type="submit" and the cancel button comes first, color and name changes are discarded when the input field is submitted via enter key.

Per the HTML spec, when you press Enter in a text field, the browser implicitly submits the form by firing a synthetic click event on the form's first submit button.

This PR changes the button type of the button with the cancel action to button instead of submit. Now, when the changes are submitted, e.g. via enter key press, the changes are getting saved correctly.
