Believe it or not, this is "normal" behavior. :-)

Let me explain... Remember that there is an inheritance chain for stuff in
Rev - if you don't set the card's backgroundcolor, but you *do* set the
stack's backgroundColor, all the cards in the stack will inherit the
backgroundColor unless a specific card has its backgroundColor set (in which
case the card's color takes precedence over the stack's color).

What you have here is the same thing, but in this order of inheritance:

  Selected Text -> Field -> Card -> Stack

So if you select text and change the text attributes of that text, it
doesn't matter that you later come along and change the attributes of the
field... the text will retain it's previously set text attributes and *not*
inherit from the field. However, if you clear out the text attributes of the
text by selecting it all and setting the textSize to empty (as you have
done), you now allow normal inheritance to continue, and the textSize can
now be inherited from the field itself.

Tricky, but it's still "normal" behavior....
