Required leading zeroes are removed from numeric object keys with compress

[alattalatta]

Describe the bug

With compress turned on, SWC optimizes numeric string keys in objects and get rid of quotes. But this behavior is too aggressive and breaks codes when the said keys start with zeroes.

Input code

const o = { '010': '', '123': 'bar' }
console.log(o)

Expected behavior

While '123' becomes 123, the '010' remains as it is.

{ '010': '', 123: 'bar' }

Actual behavior

'010' becomes 10, making o['010'] failing.

{ 10: '', 123: 'bar' }
