Background

PRs #2580 and #2635 (closing #2603) applied the if (wasVisible) setGeometry(geom) guard across most of the setFramelessMode(bool) implementations and frameless toggle sites. A complete grep of setGeometry(geom) call sites turned up four more sites with the same code-shape that were missed by both passes:

1. src/gui/ConnectionPanel.cpp:669 — `ConnectionPanel::setFramelessMode`. Unguarded setGeometry(geom) immediately after setWindowFlags(flags).

2. src/gui/AetherialAudioStrip.cpp:702 — `AetherialAudioStrip::setFramelessMode`. Same pattern.

3. src/gui/containers/FloatingContainerWindow.cpp:163 — frameless flag toggle. Inline (no setFramelessMode method), same setGeometry(geom) after the Qt::FramelessWindowHint change without a wasVisible guard.

4. src/gui/containers/FloatingContainerWindow.cpp:180 — always-on-top flag toggle. Same code-shape as the frameless toggle four lines above, different flag (Qt::WindowStaysOnTopHint). Both flag-toggle paths in this class have the bug.

Fix

Identical to PR #2580 / #2635: wrap each setGeometry(geom) in if (wasVisible) { setGeometry(geom); }. ~8 lines added across 2 files.

For the FloatingContainerWindow sites, fixing the always-on-top toggle is bundled with the frameless one because they share the exact same code-shape — saving the user pain when they toggle that flag from a cold-launched, never-shown floating container.

Verification

• Build clean.
• On macOS: open each affected window/container from a cold app launch. Pre-fix, expect top-left placement; post-fix, expect Qt's normal placement.
• Runtime frameless / always-on-top toggle should still preserve geometry on already-visible windows.

Scope and risk

• Pure mechanical follow-up to Apply wasVisible-guard for setGeometry(geom) to PropDashboardDialog, RadioSetupDialog, PanFloatingWindow #2603 — same fix pattern, no new behavior.
• Caught during stale-code audit of fix(gui): wasVisible-guard setGeometry in three more frameless toggles (#2603) #2635: PR matched the named scope of Apply wasVisible-guard for setGeometry(geom) to PropDashboardDialog, RadioSetupDialog, PanFloatingWindow #2603 exactly, but the issue's catalog of "three more sites" was incomplete.

Anyone (including AetherClaude) can pick this up.
