- Issue started after the following happened:

Reproduction Steps

• Launched mpv with --input-ipc-server.
• Sent observe_property for percent-pos and pause.
• Sent loadfile.
• Waited for the playback to finish.

Config used:

idle=yes
force-window=yes
keep-open=yes
input-default-bindings=no

Expected Behavior

Expected to receive {"event":"property-change","id":1,"name":"percent-pos","data":"100.000000"} immediately before or after receiving one for pause

Actual Behavior

Only last percent-pos before completion gets sent, while "100%" one isn't getting sent.

At least not until there's any keyboard/mouse input sent to mpv, such as moving mouse over the window or pressing any key (even without a binding).

If no input is provided (as is my case, with playback being controlled programmatically) - 100% event is never getting sent. Log below illustrates me waiting a full minute after playback finished, before i moved the mouse to trigger the evetn being sent

No response

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.
