its more than likely a common typo. while some characters do have "typing styles" that preserve a number of typos for flavor, its/it's misuse is more than likely something that would need to be fixed for ideal readability. thank you for pointing this out.
as usual, updates to the release will only be deployed if there's a sufficient number of significant bugs, but the nightly version on my website will likely have the typo fixes rolled out much sooner.
