Minor bug when adding tags

Earlier I was trying to add a Discussion tag for my community posts. And then I came across a weird problem. When I typed Di, the page would hang for a lil bit and then send me to Chrome's Aw, Snap page.

So I refreshed and tried it a few times and it kept happenning. So then I tried typing something else, and it was perfectly fine! In fact, I realized it was only if I typed the string Di that it happened. If I typed Si it was fine? After adding a random tag, adding the Discussion worked perfectly fine. Like, it seems like a super minor problem which I found a roundabout to, but just thought you guys should know.
