TYPO3 Core

I expect the 'FluidStyledContent - ListViewHelper' to return the pages in the order passed in in the parameter array.

example:
<ce:menu.list pageUids="{0: 15, 1: 10, 2: 12}" as="pages">
<f:for each="{pages}" as="page">
<f:debug>{page.uid}</f:debug>
</f:for>
</ce:menu.list>

output:
10
12
15

expectation:
15
10
12

In my opinion this should be the default behaviour. or there should be another parameter for the viewhelper: 'sortingBy'

Thanks in advance.
