Bug in test code, brought up by #90228
We need to dispose the stream from dummy request:

runtime/src/libraries/System.Net.Http/tests/FunctionalTests/TelemetryTest.cs

Line 728 in 1eb702c

await connection.ReadRequestDataAsync(readBody: false);

[ManickaP]

@karelz I'd consider fixing this in 8.0 branch as this will spam the tests.

[karelz]

Makes sense, test-only changes should have smooth ride through shiproom.
