mosstank.xml's own top-of-file comment already claimed the Advanced
Options popup "gets its own resizable=\"true\" + anchored lists" — the
popup file itself still carried the dead resize="none" attribute
(MarkupDocument.cs: "resize" only ever means anything once
resizable="true" already arms the master switch), so the claim was
false and the popup was permanently fixed-size.
resizable="true" now floors minw/minh at the pre-fix authored size
(392x450 — never shrink below the tested layout, matching the main
panel's own rule). lOptionList grows WIDTH ONLY: the value-edit field,
description, and notice all sit directly below it with zero vertical
slack and none of them anchor to shift down in lockstep, so any height
growth here would walk the list straight into the field below — the
same "grow only in the direction with nothing in the way" principle the
main panel already applies to Items/Consumables/Buffs/Route's lists.
lFilterList (the category checklist beside it) tracks the growing right
edge via its own anchor="right" so the widening option list never walks
into it, matching the main panel's own right-pinned-sibling pattern.
AdvancedOptionDescription is declared anchor="left top right" for
markup consistency, but documented as a real no-op: UiLabel.OnDraw
(UiPanel.cs) always overwrites Width/Height to the current measured
text extent on every draw, right after the anchor pass runs in the same
frame, so nothing a label's anchor computes is ever visible — a
genuinely working vertical anchor was deliberately avoided since the
notice label directly below isn't anchored either and a large resize
would walk description into it; fully anchoring the rest of the
vertical stack is a larger redesign left for a future round.
Mutation shown to fail first: reverting the markup (git checkout, patch
saved and reapplied) failed at Assert.True(built.Resizable) — the popup
was still fixed-size.
App markup/plugin filter 243 -> 244; MossTank suite holds 721/721
(this item touches App-side markup only).
