I have this for my quantity selector on a product page:
<div class="quantity"><input type="number" step="<?php echo esc_attr( $step ); ?>" min="<?php echo esc_attr( $min_value ); ?>" max="<?php echo esc_attr( $max_value ); ?>" name="<?php echo esc_attr( $input_name ); ?>" value="<?php echo esc_attr( $input_value ); ?>" size="4" title="<?php _ex( 'Qty', 'Product quantity input tooltip', 'woocommerce' ) ?>" class="input-text qty text" maxlength="12" /></div>
I just discovered this bug, only seems to be occurring in Chrome (or its a feature of Chrome?), where there are little arrows inside the box that displays the current quantity in addition to the plus/minus buttons outside of the box. The little arrows don't show in IE/Firefox, and I don't see them in my source. Not sure how to hide them. Anyone run into this before?
