I'm not sure I understand the fix. Questions inline.

Two questions:

1. It looks like `fallback` is effectively unused (always null). Did you add 
this for a future use case?
2. Unless I'm missing something, the only behavioral change is that it no 
longer executes the `if` block when the window is null if `recalculateCache` is 
false.
