rails: render variable with layout doesn't work

Question

I have the following two lines in my rails 3.2 application. The first one works, the second doesn't - the layout is not applied.

<%= render partial: 'question_pages/question_page', layout: 'layouts/question_page', locals: {question_page: question_page} %>

<%= render question_page, layout: 'layouts/question_page' %>

Any ideas on why I can't pass layout to render variable ?

Edited because of new answer: I patched Rails because I thought this wasn't possible, but the Rails devs told me better:

You can specify a layout by calling render partial: @variable, layout: 'somelayout' . Whenever you include extra options, you have to specify partial: .
