Kinsey Template: fix for Masonry grid

// Find this code in /js/components.js file
if (typeof this.onArrangeComplete === 'function') {
  this.isotopeInstance.on('arrangeComplete', () => {
    this.onArrangeComplete();
    this._equalizeColumnsHeight();
  });
}

// Fix: add a check before calling _equalizeColumnsHeight()
if (typeof this.onArrangeComplete === 'function') {
  this.isotopeInstance.on('arrangeComplete', () => {
    this.onArrangeComplete();

    if (this.equalHeights) {
      this._equalizeColumnsHeight();
    }
  });
}
