• Fix the loading indicator under MS Edge

Summary:
When creating a new Pipeline in Blue Ocean using Microsoft Edge, the spinners that display next to each stage of the process don't animate. They stay at 3:00, and remain there indefinitely.

Steps to recreate:
1. Launch Blue Ocean, and click the "New Pipeline" button.

2. Pick a place for your source code to be. I chose GitHub. If this takes a long time (which doesn't always happen), you'll see the stopped loading wheel, as below:

3. Enter a valid GitHub token. It's easy to miss this under most circumstances, because things load fast. I got lucky with this one, and caught it:

4. When you get to the point where you pick New Pipeline or Auto-discover, choose the one which will take a while. In my case, that's Auto-discover. This is a much easier way to demonstrate the stopped loading wheel:

5. You're again likely to see this once you click "Create Pipelines:"

For the entire time the screen shows "Discovering Pipelines," the loading wheel will be stopped at 3:00.
