Possible limitation on object keys

[ribeirotomas1904]

As one can see here

It appears that rescript handles object keys differently than regular strings.

When dealing with CSS modules that can cause some unexpected behaviors (the class is not set on the browser, but it works if I add the class manually on the DOM)

is this related to #6062 ?

It's not fixed by #6062 at least, so let's keep it open.
