Materialdesigninxamltoolkit: Dialog inside dialog is small

[cmeeren]

When I place a dialog inside another dialog, the inner dialog is really small:

(The "New Transaction" dialog is a UserControl that is within a DialogHost, and there's another DialogHost inside the UserControl that contains the smaller message.)

IMHO this is a usecase that should be supported, because you might have an editor (like above) that pops up as a dialog, and then a "confirm close" dialog when the cancel button is clicked if you've made edits.

It happens with both 2.4 and 2.5.

Let me know if you need a repro solution.

@cmeeren yes if you could provide a small sample that reproduces the problem that would be wonderful.

It seems to only happen when the inner dialog has IsOpen = true (either hardcoded or through binding) when the outer dialog's IsOpen is being changed from false to true. (If both dialogs are hardcoded to true, it works fine.)
