It does also depend on the width of the text because when I use 48pt in the example below
the height of the brace is always the same but with 49pt the height increases after the first page.
\starttext
\dorecurse{100}
{\startformula
\mathord
{%\setbox\scratchbox\mathstylehbox{\Umathaccent\fam\zerocount"FE3DF{\hskip48pt}}%
\setbox\scratchbox\mathstylehbox{\Umathaccent\fam\zerocount"FE3DF{\hskip49pt}}%
\the\userpageno:\the\ht\scratchbox}%
\stopformula}
\stoptext
