Description

Currently, when resolving a conversation in a PR inside the Conversation tab, the page automatically gets reloaded.
Surprisingly, when resolving a conversation there inside the Files Changed tab, then it does not get reloaded.
This is interesting as I would have expected both to use the same exact code, given that both should do exactly the same.
Would it be possible to not have to endure a reload every time a conversation is resolved in the Conversation tab, simply by replacing the currently present code with the one used in the Files changed tab?

very annoying if you got a long code review, because the page jumps to the top everytime you resolve a conversation
