Display output names increment when unplugging and plugging in the usb-c dock in which the monitors connected through
Brief summary of the problem:
I discovered this issue when un-docking and re-docking my Surface Pro 8 to it's docking station using Sway window manager. I thought this might be a wlroots issue but searching wlroots threads indicates this is likely a problem with the kernel display driver itself. (wlroots/wlroots#3560 (closed))

Observations
- When stopping the compositor and starting it again from console, the display numbers remain incremented which would imply it is not the compositor but the display driver itself. (rebooting the system causes them to detect in the original order)
- 9 out of 10 times they increment to DP-6 and DP-7, but rarely I have seen one of the two displays devices retain it's original number
- There is a similar issue opened by another user who has an AMD graphics chipset (amd#2340)
