[NTG-context] Problem with integral limits with Pagella

Hi, this gives a very bad result (the limits overlap the integral sign): \usetypescript[pagella] \setupbodyfont[pagella] \starttext \startformula \int_a^b\frac{dx}{x^2+1} \stopformula \stoptext A similar thing happens with termes, but with LM it's okay. Am I doing something wrong? -- Marcin Borkowski
