The problem is that the math parser does not know that \bfmath takes an
argument as it does not see the preamble (only math macros and what's in
lib/symbols). So it sees "\bfmath" and assumes it is a macro without
arguments, than sees the argument and drops the "superfluous" braces.
This is obviously a bug, but one that probably can't be fixed without
breaking other thing. If the braces were left in we'd end up with a lot of
really superflous braces in other places.
Try to move the macro definition from the preamble to a proper math macro
and parsing should be fine.
