Bug: runaway log on lid close/open

I've been having some issues with way-displays (1.11.0) and Hyprland (0.40.0). If I close my laptop lid all is fine:

way-displays.log on lid close

``` I [09:51:32] Lid closed I [09:51:32] I [09:51:32] eDP-1 Changing: I [09:51:32] from: I [09:51:32] scale: 1.250 (1.660) I [09:51:32] size: 1536x864 I [09:51:32] position: 0,288 I [09:51:32] mode: 1920x1080@60Hz (60,020mHz) (preferred) I [09:51:32] VRR: off I [09:51:32] (lid closed) I [09:51:32] to: I [09:51:32] (disabled) I [09:51:32] I [09:51:32] DP-2 Changing: I [09:51:32] from: I [09:51:32] scale: 1.000 (1.153) I [09:51:32] size: 3440x1440 I [09:51:32] position: 1536,0 I [09:51:32] mode: 3440x1440@60Hz (59,999mHz) (preferred) I [09:51:32] VRR: off I [09:51:32] to: I [09:51:32] position: 0,0 I [09:51:34] I [09:51:34] Changes successful I [09:51:34] I [09:51:34] eDP-1 Changing: I [09:51:34] from: I [09:51:34] scale: 1.250 (1.660) I [09:51:34] position: 0,288 I [09:51:34] mode: 1920x1080@60Hz (60,020mHz) (preferred) I [09:51:34] VRR: off I [09:51:34] (lid closed) I [09:51:34] to: I [09:51:34] (disabled) I [09:51:34] I [09:51:34] Changes successful ```

When I re-open it the laptop display never re-enables and way-display log infinitely prints the following at a rate of ~400 "Changes successful" per second:

If I kill and restart way-displays, it continues immediately printing as before. This is the log from hyprland when I do that:

I can fix it by running hyprctl keyword monitor eDP-1,1920x1080@60,0x0,1, this will immediately stop the loop, ending with:

I think it might happen in more situations, but I've only been able to reproduce it consistently by closing and reopening the lid.

This might be related to #167.
