After upgrading to Consul v1.15.0, we started to see rendering issues in UI. For example, the Services page doesn't render all list items when you navigate to the page. After opening the filters (without changing values), the missing items start to come visible. Below are two screenshots. There are 17 services in total, but only some of them are rendered first (screenshot1). After opening the filters, the page start to show all items (screenshot2). As can be seen, there are rendering issues with filters too.

The problem reproduces with latest Chrome, Firefox, and Safari.
