Using swagger-ui-dist version 3.13.5 on Windows.
Happens with chrome 65, 66 and latest Edge.
When the loading image (black circle turning around itself) is shown it gets stuck (stop cycling) and the browser doesn't respond anymore.
Happens when using OpenAPI 3 files. With version 2 of the files it is working well.
Attached is a screen shot:

I'm having a similar issue with swagger v2 file, see #4467
Hey @gonenduk, sorry for the trouble here.
I believe I've fixed the issue by testing @jemerald's example - can you give this build a try, and see if it solves your issue as well? http://crowded-squirrel.surge.sh
As for a release, I'm going to bring this up tomorrow and see what we can do to get this patch out.
Hey,
I cannot upload or access my yaml file from the build you provided, so I'm sending a minimum version of my yaml which reproduces the issue on my local machine.
Looks like it works! http://crowded-squirrel.surge.sh/?url=https://gist.githubusercontent.com/shockey/852d839ad3540c797b027281e1fe565e/raw/a8c31235c303c9f89be41cedb86d824542f0aae6/api3.yaml
Great job!
And now the obvious question: when can we have the fix? 馃榿
Looks like we will be doing a hotfix for this, so you can expect one today... right after I do some more testing :smile:
@shockey if you can, please also make a release for swagger-editor too. Thanks
