[NTG-context] does \setuplayout[grid=yes] require \startformula[split=line] ?

[NTG-context] does \setuplayout[grid=yes] require \startformula[split=line] ?

[garulfo]

Hi,

sorry for the potentially puzzling title.

I try to figure out why \setuplayout[grid=yes] seems to insert a line break in a short formula.

Is there a way of ensuring regular vertical alignment of the formula number without  ‘split=line’ ?
Many thanks for your help.

We saw something similar when working on the columnsets, but as far as I
remember it was resolved. Apparently it is not. What is (or at least was)
working was to use \numberhere instead of \startplaceformula
\stopplaceformula, so you can try

\startformula
c^2 = a^2 + b^2 \numberhere[eq:foo]
\stopformula
