Hi @jo-arroyo can you please review the changes when you have some time, I have fixed the #7111 issue using a different method so that the subsequent issue #7173 doe not happen.

[tnorling]

Why Math.max here instead of directly using indexn? What's the scenario where indexn is < 0?

[tnorling]

I also don't quite understand what's happening here w.r.t. index. Why are you looking for the index of the key, then later sorting by index? I see comments around what is happening but it would be helpful to also include comments about why

[abhixkj]

In issue #7111 , the user had reported a sample request like
https://MY_API_SITE_1/api/sites?$filter=siteUrl eq 'https://MY_API_SITE_2'
which was failing, so this logic matches the pattern for key in the URL and tries to pick the first match, I am just storing the index as 0 if no match found. All this logic to handle the request mentioned in #7111. It was difficult to explain in comments as these requests with kind of sub URL is rare. Hope you could help me with the comments.
You may check the test cases added by jo-arroyo for #7111 fix. this logic targets that fix in a way such that it does not break existing matching logic with path-scopes matching.
