inhibit_idle ignored on Fedora 32 with sway 1.4

[dekimir]

I just started using sway and swayidle, my apologies if this is the wrong repo or issue format. With X11 and i3, dpms worked exactly the way I want, without any customization: it would turn screen off after a period of idleness, but never when Netflix was playing. After transitioning to sway, I'm having trouble configuring the same behaviour.

I run swayidle to turn dpms off after a timeout, but I configured inhibit_idle on fullscreen. Unfortunately, swayidle turns dpms off even when a window is in fullscreen.

Here are the details captured right after one such occurrence:

Hm, after logging out and back in, swayidle works exactly as desired/configured. Closing...
