- Issue started after the following happened: on my 1920x1080 (scale set to 1.5) the mpv window looks so small, so i try to do geometry and it works but when setting a rule for mpv to be floating, it opens in different size then the one i set, but when no rule set for example its in tiling mode then press $mod+Shift+space to be floating it works

Reproduction Steps

1. place the following in mpv.conf
   geometry=1400x788
2. add a rule to sway to be floating
   for_window [app_id="mpv"] floating enable
3. open mpv
4. see bug

Expected Behavior

the window follow the geometry and also fix the size problem on 1920x1080 displays
(default no rules no geometry)

Actual Behavior

the window doesn't follow geometry when setting a rule

Log File

output.txt

Sample Files

geometry=1400x788

I carefully read all instruction and confirm that I did the following:

• I tested with the latest mpv version to validate that the issue is not already fixed.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• I attached the backtrace in the case of a crash.

No source file or test entry point is named. Reproduce the behavior with mpv.conf setting geometry=1400x788 and the Sway floating rule, then inspect output.txt and the window-management interaction; done means the configured geometry is preserved when the rule is applied.
