The following input field does not display the correct value in Firefox 57.0.3 (OS X 10.12.6):

<input type="number" name="id" value="20609529146343161" />

When viewed, the field shows "20609529146343200" instead of the actual value.

  • 1234567890123456 OK (increment works as expected)

  • 1234567890123.01 OK
  • 12345678901234.01 BAD
