Post Grid: Masonry grid not updating when resizing browser window

Hi, just purchased your PRO plugin, but I have noticed a small issue. When loading or refreshing the page the masonry grid works just fine, but when you resize the browser window (or do an ‘inspect element’ to test layout on mobile), the masonry grid does not update properly.

It’s like the masonry JavaScript is missing the ‘onresize’ event code to update the grid item positions when the window is resized?
