bluetooth does not work properly after waking up from suspend

[genericCandy]

When I wake my laptop (Arch, ags 1.8.0) from systemctl suspend, the bluetooth service does not work properly, and I have to restart ags.

Steps to reproduce:

• Use ags with the config.js below
• Run systemctl suspend then wake up the computer
• Connect / disconnect a Bluetooth device

Expected behavior:
The value of the label is updated

Actual behavior:
The value of the label is not updated (it looks like the widget does not receive a signal)

config.js:

const bluetooth = await Service.import('bluetooth')

const bluetooth_hook = Widget.Label().hook(bluetooth, self => {
    // print(Utils.exec('date'))
    // print(JSON.stringify(bluetooth.connected_devices))
    // print("\n")
    self.label = `${bluetooth.connected_devices.length}`
})

App.config({
    windows: [
        Widget.Window({
            name: "test",
            anchor: ['top'],
            exclusivity: 'exclusive',
            child: bluetooth_hook,
        }),
    ]
})

Even replacing the label by a button (and getting the connected devices on click) doesn't work, and since bluetooth.getDevice(...)._device also says that the device isn't connected (it is), i think it may be a GJS issue (not quite sure so i'm leaving this open)

Though it surprises me that i could not find any occurrence of this issue online, so it may be only on my machine

After reinstalling Arch, the issue still persists (i hoped that something messed with gjs / a dependency and that reinstalling could fix it, but nope).

At this point, there's not much i think i can do (I tried reproducing with only gjs, but i don't know it much (nor do i know much javascript)), so i will leave this open :(
