WebView2 making background requests to https://edge.microsoft.com/entityextractiontemplates/api/v1/assets/find-assets?name=domains_config[..]

Description

WebView2 making background requests to https://edge.microsoft.com/entityextractiontemplates/api/v1/assets/find-assets?name=domains_config[..] and then to https://edgeassetservice.azureedge.net/assets/domains_config/1.8.20/asset?sv=[..]&assetgroup=EntityExtractionDomainsConfig

Version
SDK: 1.0.1222-prerelease
Runtime: 103.0.1264.62
Framework: WPF
OS: Win10

Repro Steps

• Start fiddler or a similar MITM proxy
• Run an app that uses WebView2
• Wait for up to 6 minutes

A request will be made to https://edge.microsoft.com/entityextractiontemplates/api/v1/assets/find-assets?name=domains_config&version=1.*.*&channel=canary&key=[..]

After that, if WebView2 decides to request updated data, request to a url returned by the previous request is made (https://edgeassetservice.azureedge.net/assets/domains_config/1.8.20/asset?sv=[..]&assetgroup=EntityExtractionDomainsConfig).

The returned json appears to mostly contain regex for extracting values from an online store page (e.g. en_us_product_terms": "((add\\s*to\\s*cart)|(add\\s*to\\s*basket)|(add\\s*to\\s*bag)|(buy\\s*it\\s*now)|(buy\\s*now)|(free\\s*delivery)|(free\\s*shipping)|(estimated\\s*delivery)|(out\\s*of\\s*stock)|(in\\s*stock)|(sold\\s*out)|(add\\s*to\\s*wish\\s*list)|((fastest|express|truck|for|home))

I don't think this is a feature that's enabled in WebView2, so requests for updates should not be made.
