So looking at the description of a Sphere of Annihilation, it says:
If the sphere comes into contact with a planar portal, such as that created by the gate spell, or an extradimensional space, such as that within a portable hole, the DM determines randomly what happens [...]
Now I have seen debates about what a Bag of Holding actually is, but I'd like to know if there's a RAW answer about what happens if you put a SOA in the Bag of Holding, specifically will it potentially destroy it? More specifically:
Is the Bag of Holding considered an extradimensional space for the purposes of the random effects of the sphere?
