Improve nested Opener behavior

[Chris Mitchell]

There are cases where content displayed inside an opener may need to open further secondary dialogs. When opener is in tablet/desktop screen size mode using a tooltip dialog, for ux reasons, we don't want another tooltip dialog to appear. Instead, inside the first tooltip dialog, use overlay/transition i.e. phone screen-size opener behavior. During show, the opener should detect if it is nested, and when in tablet/destkop form factor using the overlay behavior for the nested content to open rather than another tooltip dialog.

To clarify, the second (overlay-style) opener must slide inside and from the bottom of the first (tooltip-style) one, not from the bottom of the browser viewport (see attached image).

Note that putting an overlay inside a tooltip is problematic if the overlay is bigger than the tooltip.

I spent some time looking for nested popups on my iPad and it's true that it never show two tooltips. However, the behavior of how "nested popups" are shown varies, often with the old tooltip content being completely replaced (rather than partially covered), and usually with the tooltip changing size. To see what I mean, in the Facebook app click the buttons at the bottom of the "Update status" tooltip.

Also often pressing a button in a tooltip will bring up a dialog covering almost the whole screen. For example in the Gmail app, clicking the "move" button (which is in a tooltip).

Given that no one has shown interest in creating a patch in the past 2+ years, I'm closing this as patchwelcome.
