What steps will reproduce the bug?

in Node 20.9, 20.10, 20.11:

const numberFormat = new Intl.NumberFormat('no-NO', { currency: 'NOK', style: 'currency', maximumFractionDigits: 0 });
numberFormat.format(10);
> 'kr 10' // What I expect

in Node 20.12:

const numberFormat = new Intl.NumberFormat('no-NO', { currency: 'NOK', style: 'currency', maximumFractionDigits: 0 });
numberFormat.format(10);
> '10 kr' // What I get

After the 20.12 update, the price formatting changed - kr doesn't always precede the amount.

How often does it reproduce? Is there a required condition?

I noticed this during running unit tests. 95% of the time it returns '10 kr' and when you rerun tests multiple times you will end up with the correct price format 'kr 10'.
In application, it causes a hydration error and it always reproduces.

What is the expected behavior? Why is that the expected behavior?

The expected behavior is that this new version update is not a breaking change or at least that there is info that this is a breaking change.
However, this should not be changed as I'm not sure the Norwegians started to show their prices suddenly in a different format.
I'm expecting this:

const numberFormat = new Intl.NumberFormat('no-NO', { currency: 'NOK', style: 'currency', maximumFractionDigits: 0 });
numberFormat.format(10);
> 'kr 10' // => This is how it should look like. 
// And if you try to write this in the browser console you will get the correct price format:
// Intl.NumberFormat('no-NO', { currency: 'NOK', style: 'currency', minimumFractionDigits: 0}).format(10) => 'kr 10'

What do you see instead?

I see this instead:

const numberFormat = new Intl.NumberFormat('no-NO', { currency: 'NOK', style: 'currency', maximumFractionDigits: 0 });
numberFormat.format(10);
> '10 kr' // => I'm getting price format with switched places of currency and amount

The same problem exists for Node version 18.20.0 and 18.20.1 as well (works as expected in 18.19)

This is a duplicate of #52258, #52244 and other issues.

This kind of changes are expected when ICU is updated and browsers also make them (Chrome Canary has the new behavior too).

Seeing this on my end as well. So that means browsers are going to eventually show the same style as Node 20 for placement of the currency symbol for Norwegian?
