[NTG-context] Misplaced \widehat and \widetilde in mkiv?

Hi Hans, It seems that with the latest beta mkiv, version ConTeXt ver: 2014.01.23 01:55 MKIV beta fmt: 2014.1.23 \widetilde and \widehat in mathmode are misplaced (and this is so in any of the fonts I tried). Please compare the result of the following in mkii (where everything is correct) and in mkiv: %%%% begin tilde-hat.tex \starttext We set ${\widetilde n}(t) := n(1 - t)$, and ${\widehat u}(\xi) := \int_{{\Bbb R}}\exp(-{\rm i}x\xi)f(x)dx$. \stoptext %%%% end tilde-hat.tex The attached PDF is obtained with mkiv. Best regards: OK
