On the skill earnings tab of the Alexa developer console, there is a dropdown to select the month and year for which you'd like to view earnings. The default is to the current month, and the dropdown is ordered sequentially.

Unfortunately, the dropdown's height seems to be locked to the height of the div behind it, so if the div behind it is small, several months towards the end of the year get cut off from the drop down, and there is no scroll bar (or middle-button scroll) on the dropdown, making it impossible to select the elements at the end of the list (in my case, August through December).

Additionally, that element is click-only, keyboard navigation does not give the ability to choose an otherwise hidden month. This is a fairly major accessibility concern, and it feels especially egregious considering I'd think Alexa's voice first nature might make it especially attractive to developers who are living with neuro-muscular or other motor impairments (and for whom "point-and-click" is a more challenging paradigm).
