Notice that Jacqueline can cancel Frost Tokens without resolving the "On Reveal" effect.
FAQs (taken from the official FAQ or FFG's responses to the official rules question form):
When a token is 'cancelled' or 'ignored' in its entirety (such as through Wendy Adams's ability, playing Counterspell or revealing two tokens with Grotesque Statue's ability), treat the token as if it had never been revealed at all. All of the token's effects are cancelled or ignored, and any effects that would trigger off that type of chaos token (like Baseball Bat with and ) do not trigger. However, when a token is only partially ignored or cancelled, as with Defiance, the token is still considered to have been revealed, and effects that trigger off it being revealed do trigger.
