message path with library involved

[Dr. Hawkins]

I have very recently (the last few days) started seeing handlers called
twice.

I have a custom field (a click box substitute) on a card with a behavior.

the library stack has been set to have the same behavior.

The result I am seeing is that mouseUp gets called twice--once for the
card, and again for the library.

Is this the correct result?  My understanding of the library was that it's
script went into the message path, not the stack itself, and that this
shouldn't be happening.
