Button Default Styling Changes Depending on Whether It's In a Modal/Dialog or Not

[cdaringe]

Hello:

As I went to produce a standard button (white background) in a dialog, I found that the blue button styling was applied. I expected blue styling only to be applied when using ui-button-primary.

I have taken the button element and simply moved it from the dialog to a different part of my page and seen the button return to the white background style.

I am using jQuery ui 1.11.1

On second review, simply moving the button order changed the styling. This is unexpected behavior from the modal. Would you think that this should be overruled by the theme or addressed in the jqui core?
