touchinput on wayland/sway broken after 0.38.0

[an0nfunc]

OSD does not register touchinput on wayland after 0.38.0. I could bisect it to first bad commit a140d2788c33e729c4a0867c69cfe596458653dc. Reverting this commit fixes touchinput and restores 0.37.0 behavior.

Important Information

Provide following Information:

• mpv version: 0.38.0
• Linux Distribution and Version: Archlinux
• Source of the mpv binary: repos
• If known which version of mpv introduced the problem: 0.38.0 (or commit a140d2788c33e729c4a0867c69cfe596458653dc)
• Window Manager and version: sway 1.9 + wlroots 0.17.2 + wayland 1.22.0
• GPU model, driver and version: AMD igp

Reproduction steps

1. run any build after a140d2788c33e729c4a0867c69cfe596458653dc
2. try to use the osd with touchinput on wayland+sway

Expected behavior

Working touchinput on OSD, like in 0.37.0

Actual behavior

OSD shows up, but input does nothing.
