They are misaligned with zoom set to “actual size” on my machine with the right bracket being higher than the left one.
If I decrease zoom once, they get aligned. With two or more zoom outs they get misaligned again.
If I increase zoom once or twice, they get misaligned the other way: the right bracket gets lower than the left one. If I increase it thrice, it gets aligned perfectly. Further zoom ins result in all three behaviors with no apparent logic.
