Assertion compare incorrectly colored for binary pattern

Elixir and Erlang/OTP versions

Erlang/OTP 28 [erts-16.1] [source] [64-bit] [smp:14:14] [ds:14:14:10] [async-threads:1] [jit]

Elixir 1.19.1 (compiled with Erlang/OTP 28)

Current behavior

  test "problem" do
    assert %{a: <<"test", _::binary>>, b: 2} = %{a: "test3", b: 3}
  end

  test "fine" do
    assert %{a: "test" <> _, b: 2} = %{a: "test3", b: 3}
  end

yields the following

Expected behavior

The binary pattern not highlighted in both cases

Looking at the code, we don't implement diffs for <<...>>. Which makes sense, it would not be trivial at all. I will at least add some code to disable diff in those cases, so they are not confusing.
