Steps to reproduce the problem:
1. have src/href url with credentials (https://a:b@somedomain.com/image.jpg)
2. hover over url in Dev-Tool's Elements panel
3. Profit.

What is the expected behavior?
To see https://a:b@somedomain.com/image.jpg in the popup.

What went wrong?
You see https://currentdomain.com/https:/a:b@somedomain.com/image.jpg

Notice its prepended your current domain (or file:// blar blar) to the start and also removed one of the slashes from the original protocol address. https://a:b to https:/a:b

Did this work before? N/A 

Chrome version: 58.0.3029.110  Channel: canary
OS Version: 10.0
Flash Version: 

Fails to work in both stable 58.0.3029.110 (64-bit)
and Version 61.0.3154.0 (Official Build) canary (64-bit)

Those were the limits of versions easily I have access too.

I have hosted the file on https://wormss.net/urlfail.html too. It is identical to the urlfail.html attached. Depending on what you feel more comfortable with.
