The products for review block is not working properly

Today I decided to create a template for a product review reminder letter and ran into a problem, I can’t add a block to the template that displays a photo of the product with a price with a link to leave a review. I click on it to drag it into the letter template, but nothing happens, it does not react, although the rest of the blocks are dragged normally. Watch the video, it’s more clear what I’m talking about.

I recorded a video to show the error, here is the link: https://yadi.sk/i/2wRoQ0aSr92epw
