Google Play keeps testing various UI enhancement and addition of new features every other week. Google Play Store has been testing a new UI when an user open an app store listing by clicking a Play Store link/URL from other apps. 

Usually when you open a Play Store listing, you see a full screen page with all the details and all other things. Just like these screenshots here - 


The upcoming change will show you this page as a bottom sheet and you will have two variants of of it. One which opens the app listing in bottom sheet with all the details and install button and the second one is with an "View Full Details" button which will open the full screen app listing to see all the details of the app. Here are screenshots of both types of bottom sheet - 


As you can see in above screenshots, the bottom comes with a dismiss (x) icon on top right, pressing it closes the bottom and shows you the home screen. You have to swipe back again to go back to the app from where you opened the app listing. This was not the case with the previous design and you could go back with just a single back gesture. 

Another thing is that the bottom sheet increases its height after you tap the Install button to show you ads and other recommended apps to install. 

This change isn't live yet and could be available in upcoming versions. I have spotted in the version 43.5.26-31 of Play Store.
