<option> elements can make screenshots too tall

[trotzig]

We have an example that renders a "Birthdate" selection list. This example ends up having a full rect of about five times the height of the screen. This is because <option> elements report being offset from the top by a lot.

This is an example output from logging the getBoundingClientRect() value of a bunch of <option> elements:

<option value="1905"> DOMRect { x: 455.75, y: 2611, width: 182.25, height: 21, top: 2611, right: 638, bottom: 2632, left: 455.75 } 
<option value="1904"> DOMRect { x: 455.75, y: 2632, width: 182.25, height: 21, top: 2632, right: 638, bottom: 2653, left: 455.75 } 
<option value="1903"> DOMRect { x: 455.75, y: 2653, width: 182.25, height: 21, top: 2653, right: 638, bottom: 2674, left: 455.75 } 
<option value="1902"> DOMRect { x: 455.75, y: 2674, width: 182.25, height: 21, top: 2674, right: 638, bottom: 2695, left: 455.75 }

In Chrome, these are reported differently:

VM534:1 <option value=​"1889">​1889​</option>​ ClientRect {top: 0, right: 0, bottom: 0, left: 0, width: 0…}
VM534:1 <option value=​"1888">​1888​</option>​ ClientRect {top: 0, right: 0, bottom: 0, left: 0, width: 0…}
VM534:1 <option value=​"1887">​1887​</option>​ ClientRect {top: 0, right: 0, bottom: 0, left: 0, width: 0…}

This isn't a terrible problem in v3, because the resulting screenshot will be smaller. But in v4 (beta) we're constructing a screenshot box with the full dimensions. Which makes us end up with snapshots that look like this:

You linked to localhost, so I can't see the image. Also, is this a duplicate of #136?

Lol, I wrote that up a little bit too quickly.

It's sort of related to that, but I wonder if we should just check for visibility and ignore if invisible.

This is the snapshot image. It's actually a little taller than what you see in this screenshot.
