The extension is not compatible with smart hidden panel if outer margins are zero

**Describe the bug**
If the extension is used with intellihide (panel is intelligently hidden if not in focus to allow bigger windows, present in Dash to Panel extension maintained by Zorin OS), with outer margins = zero, and if I enter edit mode, tiling shell extension insists that I must click the tiling shell icon on the panel to save or exit.

Since the panel is now a part of the screen, tiling shell overlays it, and clicking the icon is impossible (clicking divides the layout instead). Since there is no hotkey to exit edit mode, I can not exit the edit mode. Pressing Super button was a workaround to reveal the panel again and be able to access the icon

**To Reproduce**
Steps to reproduce the behavior:
1. Install Dash to Panel extension by Zorin OS
2. Enable Intellihide to hide the panel inteliigently
3. Go to Tiling Shell extension settings and make outer margins 0
4. Enter layout edit mode
5. Icon is not clickable (overlaid by the blue area).

**Information (please complete the following):**
- Tiling Shell version: 17.3
- GNOME version: 48.0`
