/*
 * A button inside an input group (e.g. "Vandaag" next to the ingangsdatum on step 3) takes the input's height.
 * The theme gives every .btn min-height: 50px and a bigger font/line-height than .form-control (0.9375rem / 2.4),
 * which stretched the whole group, input included, to 50px. With the input's font and line-height and no vertical
 * padding the button is shorter than the input, so the input sets the height and the button stretches to it.
