Can't Alt-Tab when video is paused in fullscreen

Important Information

Provide following Information:

• mpv version: 0.32.0
• Platform and Version: Windows 10 Pro,
• Source of the mpv binary: https://sourceforge.net/projects/mpv-player-windows/

Reproduction steps

Upon further testing it seems to only happen when:

1. Have gpu-api to either vulkan or opengl
2. You enter fullscreen and play the video a bit
3. Pause
4. Try to Alt-Tab

Expected behavior

When Alt-Tabbing a paused fullscreen video, the usual behavior of Alt-Tab should happen.

Actual behavior

Upon Pause, MPV freezes the paused frame. The frozen frame stays in fullscreen and you can't see the window you Alt-Tabbed to, since the frozen frame stays there no matter what.
Alt-tabbing will work again once you Alt-Tabbed back to MPV and play the video again, though it is a guesswork whether you are in MPV or not, since you only see the frozen frame in fullscreen. (Also the windows OSC like volume/brightness up/down won't show up regardless whether the video is paused or not.)
TL;DR: When you are in fullscreen and pause the video, MPV basically dies and stays on-top of all other windows so your PC can't be used anymore unless you close MPV.

Sample files

Happened with every file I tried so far.

Start by reproducing the issue on Windows 10 with mpv 0.32.0, using Vulkan or OpenGL, fullscreen playback, and a paused video; review the attached output.txt log. Trace the fullscreen window behavior during pause and Alt-Tab. Done means Alt-Tab switches to the selected window normally while the video remains paused and fullscreen.
