Bug: Visual Bug with Chrome 89

[cr3spo9]

Bug description

With Google Chrome 89, an user has reported that his calendar is seen like this:

We have been using react-day-picker for a year and it has seen the first time that we see this, and all the other users are having a good experience with it.

To reproduce

I have tried with the same version and I could not reproduce it, I dont know if you have had this issue before and know how to fix it.

Definitely not a DayPicker bug: maybe an extension installed? A wrong CSS loaded? Something failing in the build?
