### Version 5.0.3 ### Browser and OS info Chrome / Windows 10 ### Steps to reproduce 1. Create a Vuex enabled App 2. In a created component, create an `setInterval` that updates the state via a mutation at a regular interval 3. Try to inspect the Vuex state ### What is expected? If an entry in the vuex log is explicitly clicked on to be inspected, it shouldn't be changed due to a mutation. ### What is actually happening? When a mutation occurs the 'inspected' Vuex item is updated to the latest value --- I added a screen capture of what is occurring here: https://imgur.com/a/QfKAI9N <!-- generated by vue-issues.
