Fixes the OP5 (Chat tab) dual-lens review findings against e71e5a96:
- M1 (MUST-FIX): each opacity row's own apply closure now pushes its OWN
slider's thumb from the post-link truth (bindings.Current*Opacity()),
mirroring the OP4 binding pattern. Before this, a single-slider drag
followed by Reset reverted the live value/link but left that slider's
own thumb stuck at the dragged position.
- S1 (SHOULD-FIX): the Chat tab's two opacity sliders no longer round-trip
the whole settings.json on every drag MouseMove tick. UiScrollbar gains
IsDragging + a DragCompleted callback (fires once, at the MouseUp that
ends an actual thumb drag); the opacity apply closures flush immediately
when not mid-drag (Reset/Defaults/discrete edits, same as before) and
defer to DragCompleted otherwise, collapsing dozens of per-tick writes
into exactly one per drag gesture. Live opacity still applies every tick.
- S2 (SHOULD-FIX): filed register row AP-201 and issue #371 for the
UiScrollablePanel whole-row-cull-vs-clip divergence the review found
(predates OP5, made user-visible by OP5's 240-260px filter blocks). Not
fixed in this round (a renderer-level scissor stack is out of scope
here) — corrected the OP5 connected-gate script instead so a straddling
block's disappear-then-reappear-whole is no longer reported as a
self-sizing regression.
- S3 (SHOULD-FIX): the chatWindowMainFilter round-trip test already
existed in e71e5a96 (the review missed it scrolling past line 330);
added the genuinely missing coverage instead — a composed test pinning
RetailUiRuntime.MountChat's window-0 SettingsStore -> ChatWindowState
seed (MountChat itself needs live DAT access and isn't unit-testable
directly).
- N11: ScrollbarLinkage_ModelPointsAtTheChatListBoxScroll now asserts
through the scoped page-slot lookup (UiElement.FindDescendant) instead
of the flat layout.FindElement, which passed for the wrong reason given
the shared scrollbar id 0x10000201 — matches OP6's own scrollbar-linkage
test pattern.
Also updated ConfigOptionsPageControllerTests' local ChatOptionsPageController
Bindings fake for the new FlushOpacity parameter.
Full Release suite: 13,117 passed / 4 skipped / 0 failed (baseline 13,107/4/0
post-OP6 — 10 tests added, zero skips added, zero failures).
