Okay, idea time.
Sci Fi theme:
What happens when you teleFRAG a hyperspace exit portal as it forms?
What becomes of the object in transit?
It turns into a pumpkin.
How soon they forget.
An object in transit, when the transit means are interrupted, will be interrupted in transit.
The analogy is what happened to you during your ill-fated Fax Maxhine journey. Boy, were you hopping over that one!
Anyway, since the teleFRAG does fragmentation on a sub-atomic level, that portion of the object that has transported will join in the subsequent mayhem.
The portion that has not yet been transported will remain behind, divided according to the scanning sequence.
The division in "Thirteen Ghosts" comes to mind, which is similar to the fate of Kowalski on StarGate SG-1.
Equally possible is the vertical scanning sequence as displayed in "Spaceballs".
In any case, it is not healthy for the object. It is also not healthy for the hyperspace exit portal.
