Placeholder <scope.var.varname> does not work with nested variables

Title, you can't use the value of one variable to retrieve another.

Example Attached:

someskill-cast:
  Skills:
  - skill(s=someskill-exec;value=hello) @self
  

someskill-exec:
  Skills:
  - setvariable{var=caster.<skill.value>;val="yes hello hello";type=STRING}
  - message{m="<caster.var.<skill.value>>"} #this will return nothing
  - message{m="<caster.var.hello>"} #This will return "yes hello hello"

To be clear, this line:

  - setvariable{var=caster.<skill.value>;val="yes hello hello";type=STRING} @self

Works perfectly fine and the value can be retrieved with

  - message{m="<caster.var.hello>"}

However <caster.var.<skill.value>> which should be equal to <caster.var.hello> returns nothing.
