Why does a datepicker created on a detached div have zero height in Chrome?

When creating a jQuery UI datepicker on a detached div it works fine in Firefox but in Chrome it gets zero height.

$('<div/>').datepicker().appendTo('#some-element');

When attaching the div to the document first it works fine:

$('<div/>').appendTo('#some-element').datepicker();

However, since the actual code is not that simple (lots of legacy开发者_如何学编程 code, so attaching the div before creating its contents is difficult) I'm looking for a solution where the datepicker works even when created on a detached div.
