Chrome Version: 55.0.2883.95 (Official Build) (64-bit)
OS: macOS

What steps will reproduce the problem?
(1) Never use cast before
(2) Right click on any web page -> cast
(3) Try to dismiss the dialog

What is the expected result?
Since the dialog is modal, clicking outside it is expected to close it. The close button should be presented in top left corner (because I'm on using a Mac) or at least in the top right corner

What happens instead?
Clicking outside of the cast modal makes the modal jump. The UI is completely blocked. The Close button is in the MIDDLE RIGHT of the pop-up, unlike any common control I've ever seen. This makes the user actively look for this button. 

I guess accepting the prompt in the top will move the close button to its correct position, but I've clicked on Cast accidentally to begin with, why does it have to be so hard to close a dialog that I didn't even want?

But really, clicking outside of the modal should just dismiss it, and the cross should always be in one of the top corners, specifically top left on macOS.
