Marker popup closes automatically when focus-in name input

[Rplus]

When we edit name of marker,
The phone virtual keyboard will show.
And then, popup of marker will close automatically.
so, we cannot edit name on Phone deveice.

reason:
After layout size changes (keyboard show), it wil re-calculate markers in the view.
The marker will be killed when it is not in the viewport.

I think it might be fixed by enlarge calculation size.
