Wondering if I can make the bar receive pointer events and be in overlay mode at the same time

[vollowx]

I'm currently using this configuration:

{
  "layer": "top",
  "exclusive": true,
  "passthrough": false,
  "mode": "overlay",
  "position": "top",
  "height": 32,
  "margin": 4,
  "modules-left": ["tray"],
  "tray": { "spacing": 6 }
}

in order to make it for tray only.

At the same time, I want it not to influence the maxmized windows' region (by setting mode: overlay). However, after setting this, I can't reach the bar by pointer (documented as option passthrough will be enabled by default if option mode is overlay), but even I set passthrough: false, I still can't reach any part of it.

I wonder if this's the normal behavior or not. If it is, I'd like to know if it's possible to make it behave as I wanted.
