I got a suggestion once for always linking a crbug.com/xyz for TODOs, so that it
contains more context on what's going on.

there is no bug as such - I'm adding tests in a change I'm working on now so
it's unlikely that this will be lost.

+TEST(AndroidStreamReaderUrlRequestJobTest, Placeholder) {
+  EXPECT_EQ(1, 1);
