blur_xray for layer_effects

[rikutons]

Now I think layer_effects is not using blur_xray for calculating blur effect.

layer_effects 'waybar' shadows disable; blur enable

That makes not good looks like this:

(screenshot without blur, there are no border)

I guess now waybar using both under window and wallpaper rgb to calculate blur, that makes kinda shadow effect on the border. But I want borderless UI for smart-gapped window and waybar.
Can we implement blur_xray for layer_effects?
