The lines

pg/macros/core/PGML.pl

Lines 942 to 945 in 832cb29

	if ($block->{type} eq 'math' && Value::isValue($result)) {
	if ($block->{parsed}) { $result = $result->string }
	else { $result = '{' . $result->TeX . '}' }
	}

should have been removed when

pg/macros/core/PGML.pl

Lines 946 to 948 in 832cb29

	if (Value::isValue($result)) {
	$result = ($block->{type} eq 'math' && !$block->{parsed} ? '{' . $result->TeX . '}' : $result->string);
	}

where added in #981. It looks like the changes from my suggestions that removed those lines didn't make it into the actual PR.
