Studio Automations: a refused flow switch (409) shows in StudioRefusalStrip, which has no role=alert or aria-live, so the refusal is no longer announced to assistive tech — the retired Setup page announced it #29139
Description
domain:devx#1 · os-warren · session_01JQwxbZx1yZXiTrFXKbSdFZ
立卡门类别: ① 产品缺陷(用户可见的体验缺陷)— 具名落点 (ui/packages/app-shell/src/views/studio-design/StudioDesignSurface.tsx, the shared StudioRefusalStrip block, data-testid="studio-refusal") + 复现; 所需通用块: StudioRefusalStrip itself (one fix covers every pillar that renders it).
reach: 公开入口实测一次错误结果 — in the console at 7fa9873, a 409 on Studio's flow switch renders in studio-refusal with no role and no aria-live (browser run, reproduced twice).
业务理由: an admin using a screen reader who flips a flow's switch in Studio and is refused hears nothing; the switch simply does not move. Before #28785 retired the Setup › Packaged automation page, the same refusal rendered in a role="alert" box, so it was announced (the checklist item automation.setup-packaged-automation-board acceptance[5] pins that property). Moving the switch to Studio (ADR-0146 D4) dropped that property. The strip is shared, so every Studio refusal it renders is silent to assistive tech today. Not doing it: the platform's write-feedback for refusals is visual-only in its main authoring surface.
动手的读者: the domain:ui seat; triage first touch confirms the lane, then os-dev.
查重: studio-refusal role alert → 13 hits, StudioRefusalStrip → 0 hits (incl. closed): none matching. Related, not the same: #28985 (flow node inspector controls disabled with no reason exposed to assistive tech). The re-point of the Setup item to Studio is #28579, which needs this decided for acceptance[5].
QA-source: #29124 · automation.setup-packaged-automation-board · acceptance[5]
Reproduction (stock showcase, admin, console from this tree):
- Open Studio › Automations, select a packaged flow, and flip its switch (
auto-ledger-switch) under a condition the server refuses with 409 (the item's acceptance[5] admin cell stages one). - The 409 sentence appears verbatim in the element
[data-testid="studio-refusal"]. - Inspect it: no
role, noaria-live, noaria-describedbylink from the switch. A screen reader announces nothing.
- Expected: the refusal is announced (
role="alert"or a polite live region on the strip), as the Setup page did. - Actual: visual only.
Full evidence: QA run record #29124.
