Intl.Collator and natural sort with a numeric parameter are not sorted correctly with decimal numbers

Question

Sort decimal numbers with Intl.Collator, and the enable option numericincorrectly compares decimals.

In some browsers comparing “0.005” and “0.05”, “0” is returned, since the numbers are the same.

Results in different browsers:

• Chrome 54 = 0
• Firefox 49 = 0
• Edge = -1
• IE 11 = -1

// Returns 0
console.log(new Intl.Collator(undefined, { numeric: true}).compare(0.000005, 0.05))

Run codeHide result

Anyone who can tell me what's wrong?
