[NTG-context] Hat with \widehat is not satisfactory

Dear list, I think the symbol of the angles is too close to the letters. Is it possible to change this ? \enablemode[pxmath] \setupbodyfont[palatino,12pt] \starttext \startformula \sin\widehat{PAM} =\frac{AM}{PA}=\frac{\frac{\sqrt{2}}{4}}{\frac{\sqrt{6}}{2}}=\frac{\sqrt{2}}{4}\times\frac{2}{\sqrt{6}}=\frac{\sqrt{2}}{2}\times\frac{1}{\sqrt{6}}=\frac{\sqrt{3}}{2}. \stopformula \stoptext Thank you.
