Problem

src/extension.ts:2698 skips the focus handler whenever Window.clutter_focus_is_shell_panel() returns true. That helper checks both the keyboard focus and the pointer hover position (window.ts::clutter_focus_is_shell_panel), and the dock/dash app icons match is_panel_actor() (they are overview-tile actors whose ancestor is the dash).

As a result, merely hovering the dock/panel makes O-Tiling skip its entire focus handling even when a real window just gained focus.

Measured with a temporary instrumented build (log-level 4, ~1 h): 132 skips, of which 21/22 happened while a real window was focused (brave-browser, Nautilus, Terminal…). Consequences: on_focused() is not called, so prev_focused, borders and the refocus/restore logic are not updated.

Full report + evidence: #108

Fix

Only skip when the shell truly holds focus (i.e. no real window is focused):

- if (Window.clutter_focus_is_shell_panel()) {
-     log.debug(`focus-window handler: shell-panel/dock actor detected — skipping`);
+ if (Window.clutter_focus_is_shell_panel() && !(global as any).display.get_focus_window()) {
+     log.debug(`focus-window handler: shell-panel/dock actor detected (no focused window) — skipping`);
      return;
  }

This keeps the intended protection (don't process while a panel popup/menu holds focus) but no longer suppresses handling of a legitimate window focus change.

Verification

With log-level=4, hovering the dock while switching windows (Alt+Tab):

• Before: focus-window handler: shell-panel/dock actor detected — skipping fired repeatedly with a real window focused.
• After: 16 focus changes → only 2 skips, both with get_focus_window = null (the new (no focused window) message). Zero skips with a real window focused.

Fixes #108.

Thanks! I ran the project's own checks on this branch to make sure the change is clean:

• pnpm install --frozen-lockfile → OK
• pnpm run type-check (tsc --noEmit) → exit 0
• pnpm run lint (eslint src) → exit 0
• pnpm run build → exit 0 (dist/extension.js generated; verified it contains the new condition)

Live behaviour (extension run with log-level=4, hovering the dock while switching windows with Alt+Tab):

• Before: focus-window handler: shell-panel/dock actor detected — skipping fired repeatedly with a real window focused.
• After: 16 focus changes → only 2 skips, both with get_focus_window = null (the new (no focused window) message); 0 skips with a real window focused.

Note: extension.js is not tracked in the repo (it is built into dist/), so the PR only touches src/extension.ts.
