Certain PullRequest functions not working on Chrome on Mac.

I've run into a couple of bizarre issues while reviewing Pull Requests through Chrome on my Mac. 2 functions do not work that I've found so far - deleting comments, and viewing file diffs side by side. For deleting comments, I get the delete window pop up, click "Delete" then nothing happens, the comment is still there. For the diff view, again the pop up appears, but remains blank, no diff view contents.

I don't know if the issues are related, but I do know that they both work in every other scenario I tried: Safari on Mac, Chrome on Windows, and even Chrome on Mac in Incognito mode!

Especially since it worked Incognito, I tried deleting all Chrome browser site data for bitbucket, restarted the browser, but still no luck. I've attached a screen shot of the console error that happens immediately upon hitting the "Delete" button in the delete dialog pop-up. I don't get this error in the console when trying it through the other successful methods above. I suppose the other explanation could be some plug-in conflict, though I have no idea how to verify whether that's the case.

Chrome on Mac is my primary browser, so I'd love to resolve these issues and not have to use an alternative way of browsing BitBucket pull requests.
