freemarker error in simple template select.ftl when parameter multiple="true" and parameter name is missing

File : template/simple/select.ftl

Select tag does not require "name" parameter.
But when "multiple" is set to "true" the template will try to read "parameters.name"
Leading to the following FreeMarker template error :

Expression parameters.name is undefined on line 92, column 85 in template/simple/select.ftl.
The problematic instruction:

${parameters.name?html} [on line 92, column 83 in template/simple/select.ftl]
