Steps to reproduce

We tried to load this URL:

which is a Test-Endpoint to display our Maintenance-Site. It returns a 503 HTTP Status Code. When loading this URL with Edge, the first request seems (accoring to the Network Tab) never ending, so a Response Header is never available in the Network Tab (see the attached Screenshot).

If the URL is requested a second time the 503 is shown in the network tab. This can be repeated, so each first request seems to never get a response while each second request recieves one.

Another strange thing is, that the Response Header seems to be written to the html-body (according to the dom-explorer-tab, Screenshot also available). Also the box in the middle of the page always jumps around in each second request.

Thank you for taking a look at the issue!
Best Regards
