TPopup subcontrols do not accept keyboard/mouse input - (Delphi XE7 FireMonkey) - delphi

Question

I'm attempting to style a TPopup with several subcontrols, and then assign event handlers to those controls that need them (buttons primarily). I am using TPopup.IsOpen:=True.
When using TPopup.popup(True), input is detected and all mouse events work great, but I do not want the user to do anything more than "click" away from the popup window to close it.
Very similar issues found here, but there wasn't really a suitable answer other than using a modal popup.
Delphi XE5 FireMonkey TstringGrid cells don't accept keyboard input
and, this also has a somewhat acceptable answer, but my style has opaque areas that render black on a borderless form. I'd set the form's transparency, but this causes performance issues that I'd rather tackle on another day.
Allowing keyboard input to a FireMonkey TEdit nested inside a FireMonkey TPopup
Full process from start to finish:
1. set TPopup.StyleLookup:='MyStyle';
2. Assign event handlers to subcontrols
3. set TPopup.IsOpen:=True;
4. Attempt to press tab in any TNumberBox/Edit (No Keyboard input detected)
5. Attempt to click any button with assigned handler (No Mouse input detected)
Edit
After a lot of testing I was able to get mouse events to be fired for buttons, but I still cannot get user keyboard input. I've attached sample code from my tester app that opens a popup on right click
if just right click, opens standard popup with buttonstyle applied
if right click and shift, opens modal popup with buttonstyle applied
if right click and alt, opens standard popup with memostyle applied (This is the part not working)
The goal would be to allow the user to type in the popup. There is a TMemo on the form already for testing if my popup's "TMemo" will get focus after clicking the popup, and for verifying the stylenames of a standard TMemo. Also, there is a tlayout with a tmemo as a child. I used this to create a basic style that could be applied to my TPopup. (Please forgive any poorly named variables or unused code... I've tried a lot of different things with little luck.. I'm not really sure where to start and what to toss)

Decided just to go with this answer here:
Allowing keyboard input to a FireMonkey TEdit nested inside a FireMonkey TPopup
For transparency, I added a child TPanel on the fmPopup form named Content. Afterwards I set the Transparency:=True, and applied my custom style to the Content panel. Not exactly what I wanted because I had to write my own positioning/hiding procs that a TPopup already had, but my existing "initialize style" procedure worked without any modifications. I certainly welcome any better solutions.
