Yes, the genetics are for shorter, stockier plants. The Dwarf Tomato Projects used dwarf plants like New Big Dwarf and crossed them with tastier heirlooms, then took the best of the offspring and crossed them, etc. Some varieties may be more stable than others. I wonder if your plants got a lot of nitrogen to push leaf and stem production? Even so, I'd expect longer lateral branches rather than additional height as such...
Maybe we should try to pull
@Dave into this discussion (you know, because he has so much free time LOL). He may already be lurking...
