To make this concrete, here's a testcase:
https://bug1867106.bmoattachments.org/attachment.cgi?id=9365919
The relevant style rule there is `@page { size: 3px }`, and if you view the output in web console, the last bit of logged output tries to get the value by logging this expression:
```
document.styleSheets[0].rules[3].style.size
```
In Firefox, this reports `undefined` for reasons that Emily discussed above, which we think is correct, since `.size` isn't available on the interface. But Chromium/WebKit have it there anyway, and they log `3px`.
In Firefox, the following longer version with `getPropertyValue` does get the value as-expected:
```
document.styleSheets[0].rules[3].style.getPropertyValue("size")
```
so I think that's what web developers are currently supposed to do, but the fact that `.size` works in other browsers (and feels less-clumsy) makes it tempting to make that officially work for this situation.
