I forgot to update with the fix. In includes/functions.php, replace:

if ( is_same_day_event( $event ) ) {
    $start_date = get_event_start_date( $event, false, $format );
    if ( is_all_day_event( $event ) ) {
        $separator = '';
    } else {
        if ( $show_time ) {
            $start_date = get_event_start_date( $event, $show_time, $format );
            if ( '<br>' === $separator ) {
                $end_date = get_event_end_date( $event, $show_time, $format );
            } elseif ( $show_time ) {
                $end_date = get_event_end_time( $event ); // ← PROBLEM HERE!
            }
        } else {
            $separator = '';
        }
    }
}

with:

if ( is_same_day_event( $event ) ) {
    $start_date = get_event_start_date( $event, false, $format );
    if ( is_all_day_event( $event ) ) {
        $separator = '';
    } else {
        if ( $show_time ) {
            $start_date = get_event_start_date( $event, $show_time, $format );
            if ( '<br>' === $separator ) {
                $end_date = get_event_end_date( $event, $show_time, $format );
            } else {
                $end_date = get_event_end_time( $event, $format );
            }
        } else {
            $separator = '';
            // Ensure we're not showing any time components
            $start_date = get_event_start_date( $event, false, $format );
        }
    }
}
