Field-hit on LL Albums grouped (alpha): deriving each section grid's
content-offset from an absolute-position DELTA binding panics with
'Recursion detected' (i-slint-core properties.rs:583). Evaluating the
target-row chain through absolute-position can land inside the parent
layout solver's own pass, and the grid's height/columns read back
self.width — re-entry. The Timer-seed guard only covered init-time
reads, not binding-evaluation context. Grouped windowing needs
Rust-computed per-section offsets (backlog); the flat grids — the big
win — keep their windowing unchanged.
