Describe the bug you're encountering

oAuth2 redirect page does not work with Internet Explorer 11, the redirect page get stuck on an empty webpage (oauth2-redirect.html) with an error (in french sorry):

SCRIPT5007: Impossible d’obtenir la propriété  « swaggerUIRedirectOauth2 » d’une référence null ou non définie

It says 'Impossible to obtain the property "swaggerUIRedirectOauth2" from a null or undefined reference'.

To reproduce...

Try to use oAuth2 with Internet Explorer 11

Expected behavior

I except the window to close and be back authenticated on Swagger UI interface (like in Chrome).

Additional context or thoughts

It seems that window.opener is undefined in Internet Explorer which cause this issue

[jeremymeng]

Hit this too. Are there any workarounds?

[sonphnt]

I have the same issue too. window.opener is null in IE11 and Microsoft Edge. Do we have a solution for this?

[jurepurgar]

Same problem here. I found out that adding the page to the "trusted sites" in IE resolves the problem for both IE and Edge.

[patricknolan]

Same issue here. Any resolution for this one? This should be a high priority issue if oAuth2 fails when using IE.

IE is no longer supported. https://github.com/swagger-api/swagger-ui/issues/5808#issuecomment-576953636
