pub const MAX_VIEW_DEPTH: usize = 128;Expand description
How deep a Lua view tree may nest: twice deep_nesting_64_levels,
and inside a debug build’s 2 MB test thread whatever the nodes on the
way (a chain of tooltips, radio groups and fragments overflowed it
between 128 and 256). Past it, or on a node that is its own ancestor
(t[1] = t), [build_node] refuses the view rather than recurse off
the stack (backlog RG95).
