coord2norm not providing correct location to annotation built-in

[sco1]

Passing normalized coordinates to annotation does not produce the axes position for the annotation.

For example:

myaxes = axes();
x = 0:10;
plot(x, x);

[normx, normy] = coord2norm(myaxes, 2, 6);

dim = [normx normy .3 .3];
mystr = 'This is plot 1';
annotation('textbox', dim, 'String', mystr, 'FitBoxToText', 'on');

Rather than placing the corner of the text box at [2, 6] as desired, the annotation is placed around [2, 9].

However, the norm2coord inverse provides the correct location:

hold on
[coordx, coordy] = norm2coord(myaxes, normx, normy);
plot(coordx, coordy, 'o');

hold off

This is an issue with the 'FitBoxToText' property of the annotation edit box. If you set this property to the default 'off', the box is positioned appropriately on the figure:

myaxes = axes();
x = 0:10;
plot(x, x);

[normx, normy] = coord2norm(myaxes, 2, 6);

dim = [normx normy .3 .3];
mystr = 'This is plot 1';
annotation('textbox', dim, 'String', mystr);

However, when resizing the border to the text, the annotation object is not repositioned to account for the border change. As this is an internal MATLAB issue this is beyond the scope of the functions in this repo.
