What steps will reproduce the bug?
In node:12.19.0-slim docker image setTimeout function returns a value for which isNaN=false
In node:12.18.4-slim docker image setTimeout function returns a value for which isNaN=true
timeoutId = setTimeout(function() {alert("Timeout")}, 1000);
console.log(isNaN(timeoutId))
Is this an intentional behaviour?
