Floating windows always on top ("Activate windows on hover")

**Is your feature request related to a problem? Please describe.** This issue is regarding to when "Activate windows on hover" is active: Floating windows often get hidden in the background when moving the mouse around (other windows get focused). This is especially annoying when a window spawns as floating and the mouse is at a different location -- it will get hidden behind the tiled windows and there is no practical way to get it back to the foreground, except for pre-moving the mouse to the correct location and `alt+tab` to activate the window. Also, this issue is more sever when the floating window is small of size, or entirely overlapping with a tiled window. A case where this issue is also very annoying is when the OS spawns floating windows, for example context menu action windows, e.g. right click on file -> "open with" -> "choose another app". These windows are naturally small of size and get almost immediately lost in the background behind tiled windows. To reproduce an example, simply: 1. Set the "Activate windows on hover" setting 2. Spawn a window and setting it to floating mode by pressing `win+shift`, `F` 3. Move the mouse around (focus other windows) **Describe the solution you'd like** I would like to request a feature of having floating windows "always on top", regardless of which window is focused at the moment. This is a feature for many tiling window managers on Linux and I think a lot of users accustomed to a tiling window manager workflow would expect and appreciate this behavior with FancyWM. **Describe alternatives you've considered** One solution would be to disable the "Activate windows on hover" feature. One downside of this solution is, that this would introduce a compromise for users liking the feature, having to choose between having auto-activation of windows vs. proper floating window behavior. If it is not a limitation on the OS side, adding the feature of floating windows always being rendered on top would be a nice, or even necessary, feature for users wanting to use floating windows as well as the "Activate windows on hover" setting. **Additional context** I tried starting FancyWM as administrator, to investigate whether FancyWM has implemented this behavior but it was an issue due to missing privileges; also with administrator privileges, this issue persists.
