Note that the test was running under Fuchsia/x64, which runs in QEMU+KVM, with nested virtualization on our bots - so this may be a timing-specific flake.

At first glance, I don't think it's related to the stream dependency stuff; neither HEADERS nor PRIORITY frames are sent in this test. Also, the instantiated tests with an even-number index ("/10", in this case) have client_headers_include_h2_stream_dependency_ set to false.
