Panel layout resets after external monitor connection

[xalt7x]

Describe the bug Dash to Panel has an option "Apply changes to all monitors" (panel-element-positions-monitors-sync). Unfortunately after yours first external monitor connection panel layout (left/right/top panel location, elements position & stacking) get reset to default values. That happens even with disabled option "Display panel on all monitors" (multi-monitors). After you tweak panel layout once again it would stick (at least for 2 displays).

How to reproduce

1. Disconnect all external displays ; close extension settings window, [optionally] reload GNOME Shell
2. Reset extension settings gsettings --schemadir ~/.local/share/gnome-shell/extensions/dash-to-panel@jderose9.github.com/schemas/ reset-recursively org.gnome.shell.extensions.dash-to-panel
3. Disable "Display panels on all monitors" (via dconf or with a CLI command) gsettings --schemadir ~/.local/share/gnome-shell/extensions/dash-to-panel@jderose9.github.com/schemas/ set org.gnome.shell.extensions.dash-to-panel multi-monitors false
4. Change some layout settings on a "Position" tab (e.g. place panel on the left side of the screen, select "Monitor Center" element position for "Taskbar")
5. Connect external monitor

Expected result Dash to Panel preserves previously tweaked panel layout

Observed result Panel layout resets to default values (panel at the bottom of the screen, "Taskbar" element stacked to left etc)

Linux distribution and version Ubuntu 22.04

GNOME Shell version 42.4

Dash-to-Panel version 52

Where was Dash-to-Panel installed from? Extension Manager

I can't reproduce on Ubuntu 22.04 following your steps, for me the panel keeps its settings.

Prelude

I want to add that the "Display main panel on" option is reset as well when turning off and back on a DisplayPort monitor. I have the panel only on a smaller monitor (2), connected via HDMI, and no panel on a bigger monitor (1), connected via DisplayPort.

Unexpected Behaviour

Dash to panel is set to "Display main panel on" "Secondary monitor", showing only on (2). When I turn off (1), then turn it back on, "Display main panel on" is reset to "Primary monitor", showing on (1). I would expect it remembers to be shown only on (2).

Supposed Problem

I assume this behavior is caused because (2) becomes the primary monitor when (1) is disconnected, so "Display main panel on" is automatically set to "Primary monitor". When reconnecting (1) it is again the primary monitor, the "Display main panel on" is still on "Primary monitor", so shows on (1).

(1) My bigger main monitor (2) My smaller secondary monitor

I have also problem with panel positions and thickness after switching office/home. At the office I have laptop open + 2 external monitors = laptop monitor, recognized as no.1, is primary one and the dock has position: right. First external, no.2, position: right. Second external, no.3, position bottom. At home I have laptop monitor (no.1, primary) + one external (no.2) and there is a problem with primary laptop monitor - the dock is bottom, not on the right as it should be. External monitor is ok, has a dock on the right. It seems after I switch to home the primary dock gets a position either a thickness of the dock from 3. monitor at a office. Ubuntu 23.10 Dock version 60
