Single product page has huge space until image gallery clicked or browser resize

Hey All,

I have this strange problem that emerged after the latest WooCommerce update. I’m running a Storefront theme. When you visit the single product page, there is a significant space between the main product image and the product image grid (1000+px). This gap goes away when you

1. Resize the browser window
2. Click on one of the other images

I’ve been unsuccessful in finding a fix anywhere so far, though that may be due to my lack of google-foo. I’m unsure how to debug this beyond what I’ve already done.

* Ensure that my template files are up to date
* Ensure that there’s nothing happening with other plugins that might cause this issue
* Ensure everything is updated correctly.

Any help would be greatly appreciated.
