Set Text Size is empty but then not empty

Yes, we understand that chunks retaining their textProps is "normal  
behavior"

What doesn't make sense is that in fact the above does not *really*  
work.. or rather, it works only "momentarily."

try the following and you will see what I mean:

1) make new stack
2) create fld "field1"
3) create fld "field2"
4) from msg:

put "Fly with Rev--Free at Last!" into fld field1
put "Fly with Rev--Free at Last!" into fld field2

5) make button1 "set Size"

on mouseup
         set the textsize of fld Field1 to 18
         set the textsize of fld field2 to 18

end mouseup

test: it works.. as expected... text in both fields changes to 18 pt

Now:

6) manually select the text of fld field2 and set the font size to 12.

7)  now click button "set size"; Text of field2 retains it's 12 pt  
size.  Normal behavior. As expected, the chunk was manually set and  
therefore  retains it's font size...

8) make new button2: "clear size"

on mouseup
     set the textsize of the selectedtext to empty
end mouseup

Make sure it's traversal on is set to false;  select the text of fld  
field2 and click "clear size" and it will change to 18 point. As  
expected... it inherits the prop we set with btn 1 above. And you are  
thinking "See, yep, it works as expected..."

"But wait.. . there's more!"

Enter the green gremlin  :-) :

9) edit script  of btn "set size" change the point size to 12

on mouseUp

   set the textsize of fld Field1 to 12
   set the textsize of fld field2 to 12

end mouseUp

click that button again... note this time field2 retains the point  
size of 18... i.e.  even though we had just a moment  ago set the  
textsize of the text itself to empty, it now longer inherits the  
textsize of the fld as set by script as it did when we started. It   
work at stage 5) above.

Having "touched" the prop of the chunk, just once, it no longer  
behaves as expected, even having set the prop to empty.

So, question remains: how to get the field and the text inside it  
back to its original "pristine" state, where the cmd "set the  
textsize of fld field2 to 12" will be effective?

Of course Sarah's work around will work

set the textsize of  fld da to tSize
set the textsize of char 1 to char -1 of fld da to tSize

but it begs the question
