Slack Selector - Flag icons shows only letters on Windows

[raphaelspimenta]

Describe the bug
First of all, thanks for sharing this work. It's amazing!

I installed the library on my project, and it's working fine! But on the Windows Chrome browser, it seems that the flags on SlackSelector are not working properly. Instead of showing the flag itself, it's showing letters.
When I check the network request, the fonts are being loaded correctly.

I'm not sure if it's an expected behavior and it's really complicated to debug. So, any idea of what the issue might be will be very helpful.

To Reproduce
Steps to reproduce the behavior:

1. Standard installation on a React project
2. Use SlackSelector on a component
3. Check the flags on a Windows machine

Expected behavior
I was expecting that the flags would show up instead of letters
