[Android] - At some zoom in, map pan, screen pan, textbox scroll interact in a very glitchy manner

It's hard to describe what actually happens, but here's how to reproduce:

1. Zoom the screen in a little.
2. Drag the finger around in circles on the text box.

It should affect only the text box scroll, or at worst the text box scroll and the screen pan.

But for some reason it also moves the map around, and even in an unpredictable manner.

In retrospect and trying on a bigger device this seems to be because the three drag modes don't capture the drag exclusively, so you can move from one drag mode to the other and cause, when moving in big circles, very illogical input data.

Sorry for the glitchy UI. Just to make sure I understand, this is basically a problem with the zoom window and other scrollable UI elements competing for input, right?

E.g. if you zoom-in and start panning around, it works normally until a scrollable UI thing appears in the zoom window, and then panning stops while the scrollable UI thing takes over?

If so, this might not be too hard to fix. We might just need to disable scrolling UI widgets while zoomed-in.

Let me know if I've got the details right. Thanks!
