Multiple Buttons to Single Window

[mpboyle]

I have an experience where I'm hoping to use multiple buttons to open the same anchored window on different pages, kind of like a dropdown list that will launch other pages.

This seems to work sometimes, but other times when I click the button, the anchored list is displayed as expected, but then a second window is opened off to the side.

Is this a bug?  Is this functionality not supported?  Do I have to create a separate window for every page?

Maybe this is because it's the draft version...?  If I view the published version, it seems to work as expected.
