Summary0008308: Strange interactions between trees and bridges
DescriptionBridges can be built in trees (supported by branches or trunks) without harming the tree. I found two issues, both presumably caused by strange interactions with tree parts:
1. tiles under a bridge only count as "inside" if those bridge tiles were constructed over "open space". Bridge tiles on branches or twigs have "outside" tiles underneath.
2. bridge tiles constructed on twigs cannot be crossed by dwarfs.

I suspect bridges don't assert their presence when intersecting with trees (which might be why they can be built there in the first place).
Steps To ReproduceAccess the higher levels of trees via ramps/stairs. Build bridges there. Observe inside/outside patterns on the levels below, check access/movement on the bridges.

Looking through other reported bugs, this one might be related to Issue 0007872 - bridges not counting as solid constructions may be why trees can grow through them.
