I guess I see the following problems:
0 - it's not clear to me why Emacs chooses to split B rather than A.
It seems unrelated to the split-height-threshold fix, so we need to look
into this before being able to determine how best to fix it.
1 - since we're in buffer/window A, it would probably be preferable to place
buffer C closer rather than further, so in this case after splitting B
display-buffer should prefer using the top window for C and the bottom
one for B.
2 - "dedicated" is mostly meant to cause deletion of the buffer to also
cause deletion of the window. It says nothing about the window having
a fixed size or being non-splittable.
3 - we have window-size-fixed for that.
4 - we don't have window-(un)splittable for that (there's a frame parameter
to prevent splitting windows in that frame, tho).
