Need Urgent fix for CookieHeaderParserShared throws exception when last cookie contains invalid character in .NET7

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

#45127 related to this issue Fix CookieHeaderParserShared throws exception when last cookie contains invalid character and this #45014

I confirm that there is an issue in NET 7 and that the Asp.net core code has to be fixed. We cannot wait for the release of NET 8.

Expected Behavior

CookieHeaderParserShared.CookieHeaderParserShared Shoul not return true from this line https://github.com/dotnet/aspnetcore/blob/v7.0.1/src/Http/Shared/CookieHeaderParserShared.cs#L75

because it will make this code thrown the exception

Steps To Reproduce

Change ParseManyCookies unit test to below code

  [Fact]
    public void ParseManyCookies()
    {
        var cookies = RequestCookieCollection.Parse(new StringValues(new[] { "errorcookie=dd,:(\"sa;" }));

        Assert.Equal(12, cookies.Count);
    }

Exceptions (if any)

unit test : https://github.com/dotnet/aspnetcore/blob/v7.0.1/src/Http/Http/test/RequestCookiesCollectionTests.cs#L43

.NET Version

7.0

Anything else?

No response

@Tratcher if this is common, we might want to revert this change. I’m thinking about the YARP scenario and people using ASP.NET Core as a gateway

@davidfowl @Tratcher I found this code was remove from dotnet bot here https://github.com/dotnet/aspnetcore/pull/35547#discussion_r701222376

FYI. We are decided to roll back the production version from .NET 7 to.NET6
