Also the itemize environment is broken too (perhaps same issue is here too):

\setupdirections[bidi=global,method=default]

and if I swap right and left parentheses, I get the following error:
thanks for testing
the problem is that sometimes it's hard to deduce the state so i've added
\righttolefthbox \rtlhbox
\lefttorighthbox \ltrhbox
\righttoleftvbox \rtlvbox
\lefttorightvbox \ltrvbox
\righttoleftvtop \rtlvtop
\lefttorightvtop \ltrvtop
\autodirhbox
\autodirvbox
\autodirvtop
some cases are (using the default parser, which is a one-pass forward
scanner) tricky to determine
\hbox{\righttoleft(0001)}\par
\dontleavehmode\hbox{\righttoleft(0002)}\par
{\righttoleft(0003)\par}
{\righttoleft(0004)}\par
\dontleavehmode{\righttoleft(0005)\par}
\dontleavehmode{\righttoleft(0006)}\par
\rtlhbox{(0007)}\par
\ltrhbox{(0008)}\par
\dontleavehmode\rtlhbox{(0009)}\par
\dontleavehmode\ltrhbox{(0010)}\par
\hbox{(0011)}\par
\dontleavehmode\hbox{(0012)}\par
the other parsers do several passes and are slower can can handle some
cases better
anyway, it would be nice to see where the three methods fail:
\setuplayout[middle]
\starttext
\setupalign[r2l]
\definefont[arabicfont][Arial*arabic at 20pt]
\enabletrackers[typesetters.directions.default]
\enabletrackers[typesetters.directions.one]
