Review comments at @src/ui/windowChrome/useTransparency.ts:
- Around line 26-45: Remove the module-level `ipcRenderer` import from
`useTransparency.ts` and use the existing `RocketChatDesktop.logViewer` bridge
for the subscription. Preserve legacy IPC behavior only if needed by injecting
the subscription function from callers; ensure the module can load without
requiring `electron`.

15-18: 🎯 Functional Correctness
TRANSPARENCY_CHANNELis'log-viewer-window/transparency-changed', and that exact channel is allowlisted. The Log Viewer listener therefore is not blocked. The comment on'transparency-enabled'is inaccurate, but it does not cause the claimed failure.

cloneArg.
JSON.stringifyreturnsundefinedfor functions and symbols.JSON.parse(undefined)then throws aSyntaxError. Circular objects andBigIntvalues also throw. Ininvoke, the error rejects the returned promise, so callers do see it. InsendSync, the error propagates synchronously. This happens for any caller passing such a value, even to an allowlisted channel. Current callers pass plain objects, so the risk is low. UsestructuredCloneor wrap the call in a guarded helper to give a clear error.Proposed fix

- Around line 15-19: Move the legacyWindowBindings import before the
../ui/windowChrome/styles import to satisfy import/order. Apply this change in
src/documentViewerWindow/DocumentViewerWindow.tsx (lines 15-19) and
src/downloadsWindow/DownloadsWindow.tsx (line 36).
Review comments at @src/downloadsWindow/DownloadsToolbar.tsx:
- Line 5: Format the import from legacyWindowBindings in DownloadsToolbar by
splitting its named imports across multiple lines to satisfy Prettier.
Review comments at @src/settingsWindow/SettingsWindow.tsx:
- Line 12: Reformat the import of legacyInvoke, legacyMaximizedSubscribe, and
legacyTransparencySubscribe into a multiline import and move it before the
../ui/windowChrome/styles import to satisfy import/order and Prettier.
Review comments at @src/ui/windowChrome/logViewerBridge.ts:
- Around line 39-42: Update the return type formatting in getLogViewerBridge to
keep the function signature, including “LogViewerBridge | undefined,” on one
line; leave its existing return expression unchanged.
Review comments at @src/ui/windowChrome/WindowControls.tsx:
- Around line 57-59: Add rejection handling to the is-maximized invoke chain in
WindowControls so a rejected invoke does not become unhandled and the maximized
state remains at its default; preserve the existing isCurrent guard and
successful result handling.
- Around line 67-70: Format the subscribeFn call that assigns unsubscribe on one
line with its channel and callback arguments, matching the project’s Prettier
style.
Review comments at @src/ui/windowChrome/WindowToolbar.tsx:
- Line 21: Move the BridgeInvoke and BridgeSubscribe import in WindowToolbar to
the top-level import section, before the ./styles import, so it precedes all
non-import code and satisfies import ordering.

Ref #3377, split from #3563.
Enables context isolation and disables Node integration for the LogViewer secondary window (RFC #3377 Part C).
To support this without breaking shared UI components:
logViewerBridgeto abstract IPC access.WindowControlsanduseTransparencyto prefer theRocketChatDesktop.logViewerbridge, falling back to a lazywindow.require('electron')in non-sandboxed contexts. This avoids the top-levelrequire('electron')bundle crash that CodeRabbit flagged.secondary-window/*) andwindow-maximizedto the preload IPC allowlist.
