Is this really a typo? Maybe I'm wrong but the sentence seems to read fine without changing by -> to?

[agarwalrounak]

The preposition after visible is usually to when referring to something being visible to someone.

So it's not really a typo but more of a preference?

[agarwalrounak]

Yes, it's more of a preference and I have changed the commit message accordingly.
