[Dev-luatex] Wrong default value for \Umathradicalrule ?

Per LuaTeX manual, \Umathradicalrule is equivalent to OpenType
RadicalRuleThickness but the comment in page 111 doesn't seem right to
me; RadicalRuleThickness, from its name, is the thickness radical rule
and thus it should default to default_rule_thickness as TeX82 does and
as recommended in OpenType MATH specification too.
In short, \Umathradicalrule should be the same as, say,
\Umathoverbarrule but it isn't:
\the\Umathradicalrule\textstyle : \the\Umathoverbarrule\textstyle
