Chart preview not showing on Linux

[vsaw]

Reported by @rochelmeyer (@thorsten4future@climatejustice.social)

Linux, KDE neon (basically ubuntu with the latest KDE Plasma Desktop on top) not somethin that lets you run into problems frequently.

Icon itself seems to be working and changes color depending on grid usage.

OK, so it turns out ElectronJS does not support mouse-enter events on Linux for Tray icons.

The workaround of opening the chart preview on click is also not possible because I cannot determine the location of the Tray icon on screen and therefore don't know where to show the preview. Things I tried so far:

• Looking at the click event bounds and position seems to be broken, as it always returns 0 for bounds and position coordinates.
• screen.getCursorScreenPoint() is broken as well on Linux. See https://github.com/electron/electron/issues/42519

Therefore, I don't know how to fix this at the moment and probably cannot until upstream Electron is fixed.
