In Chrome, the console.log at note 1 results in:

    [1: option, 2: option, 0.75: option, 0.375: option,
    0.625: option, 1.5: option, 1.25: option, 1.75: option, 0.5: option]
    >
    >0.5: option
    >0.75: option
    >0.375: option
    >0.625: option
    >1: option
    >1.5: option
    >1.25: option
    >1.75: option
    >2: option
    length: 3
    >__proto__: Array[0]

Where the > is a expand/collapse-able arrow that expands/collapses what is below it. Clicking and of the sub >'s expands that full object - with all of the properties you would expect from an option object.

However, the length of the array appears to be 3.

In Firefox, the log shows this (same behavior as chrome, but with + instead of >)
The two options in the parent correspond with the option at value 1 and 2.

    +[undefined, option, option]
    	+0.375	option
    	+0.5	option
    	+0.625	option
    	+0.75	option
    	+1	option
    	1.25	option
    	1.5	option
    	1.75	option
    	2	option

Note 1 and note 2 result (respectively) in this:

    0:undefined
    1:<option value=​"13">​1"​</option>​
    2:<option value=​"21">​2''​</option>​

and this:

    0:undefined
    1:[object HTMLOptionElement]
    2:[object HTMLOptionElement]
