Batch E's UiButton.DrawBlockLabel/WrapBlockLines auto-wrapped any caption
that didn't fit its box width — decomp-wrong. UIElement_Text::
CalcJustification @0x00467260 (shared by GlyphList::Recalculate's
horizontal/vertical branches) shows retail's real per-glyph break decision
(both the width-triggered wrap AND the explicit-newline break) sits behind
ONE gate keyed on the OneLine flag; nothing in the decomp confines a
caption's wrap width to a sibling element's rect (Batch E's own ValueBox
confinement for the coexisting-value-label shape).
Live-DAT evidence: the Coordination attribute-slider label (0x100002ed)
authors OneLine=true (should never wrap); the Skills credits button's
"Available Skill Credits" caption measures 193px against its own full
231px button width (fits comfortably) — the 113px confined width Batch E
fed the wrap decision was never a real retail quantity.
Fixed: WrapBlockLines now splits ONLY on the explicit (already-normalized)
'\n' — never width-based. Strict superset of the pre-Batch-E single-line
draw for every already-correct caption; "Attribute\n Credits" still works.
The ValueBox confinement computation stays in OnDraw (still feeds the
Center-alignment tx formula) but no longer gates the wrap decision.
