The space lost after the colon in getAllResponseHeaders()

[ewfian]

I found that The return value of polyfilled getAllResponseHeaders() will not same as native, it will make some thing broken.
I have created a pull request to fix this : #67

1. The origin http header
   

2. Parsed response header
   

3. The return value of polyfilled getAllResponseHeaders()
   The space lost here
   

4. The FIRST CHAR LOST.
   Some 3rd libraries like azure-sdk-for-js makes http request by using XMLHttpRequest and parses header by itself just like following code
   https://github.com/Azure/azure-sdk-for-js/blob/744e51acb755db2c565c71a8856d8d13e6ec345b/sdk/core/core-https/src/xhrHttpsClient.ts#L129
   If the return value from the polyfilled function XMLHttpRequest.getAllResponseHeaders() is not keeps the exact same format (Date: Thu, 01 Oct 2020 05:18:27 GMT\r\n) as the original value, some thing will broken.

Thanks for response.
Here is the spec of getAllResponseHeaders() : https://xhr.spec.whatwg.org/#the-getallresponseheaders()-method
(From Azure/azure-sdk-for-js#11581 (comment))

You can find that followed by header’s value, followed by a 0x0D 0x0A byte pair also need to fix.
