/* Notably absent is the part where we notify the chrome window using
GetBrowserChrome()->SetChromeFlags(). Given the possibility of multiple
DOM windows (multiple top-level windows, even) within a single
chrome window, the historical concept of a single "has scrollbars"
flag in the chrome is inapplicable, and we can't tell at this level
whether we represent the particular DOM window that makes this decision
for the chrome.
So only this object (and its corresponding DOM window) knows whether
scrollbars are visible. The corresponding chrome window will need to
ask (one of) its DOM window(s) when it needs to know about scrollbar
visibility, rather than caching its own copy of that information.
