Research direction
Inspect the Rust implementation of the Access-Control-Request-Headers value and compare its joining behavior with the Fetch CORS specification and the linked web-platform-tests test. Done means header names are joined with commas only, without spaces, and the strict WPT case passes.
Written by the indexing model from the issue text.
Description
The Fetch CORS spec specifically notes that the header list that is the value of ACRH does not use combine and only uses , (comma) to join the header names.
MDN's example value for this header also does not use spaces.
The WPT test https://github.com/web-platform-tests/wpt/blob/master/xhr/resources/access-control-preflight-request-header-sorted.py tests for this strictly.
