Dear List,

After compiling the following example, which is from February 2021:
\setuppapersize[A8,landscape]
\setuplayout[leftmargin=2.5cm,
             leftmargindistance=0.2cm,
             backspace=2.9cm,
             width=4cm]
\showframe
\starttext
\margintext{\hairline\\{Me}}\dontleavehmode\hairline
\startformula
a^n + b^n = c^n.
\stopformula
\stoptext





I get:
