Steps to reproduce:

1. From here I can toggle the Blame button and the screen dynamically updates and, as expected, shows and hides the Blame annotations as I continue clicking the Blame button.

2. However, when I drill down on a commit and get to the Diff view like this one, the screen does NOT dynamically update as I click the Blame button. The Blame annotations DO show up (or hide, depending on which Blame toggle to which I've clicked) if I Reload the browser page (command-R). The issue is that the page will not dynamically update.

Here is a link to a screen recording where I'm showing the above 2 scenarios.

Expected behavior:
