if you navigate to an issue from a different page on github the +1s are not shown on top

for example if you click this link: #1

you wont see any +1s near the title
however if you refresh the page when viewing the issue it will display correctly.

The MutationObserver needs to look at the whole page to see if it changed, not just the .js-discussion element.
