Reproduction steps

Set the pause property to true, time-pos to any valid value and vf to {}.

Expected behavior

mpv should seek to the second specified by time-pos.

Actual behavior

mpv pauses the video at the current position, without seeking. (actually, the log says it seeks to the current position, I don't know if this is useful or not).

Look for "pause_seek" and "unpause_seek" for relevant output.

Sample files

Used the following Lua script to reproduce, "1" causes the bug, while "2" works property:

function pause_seek()
	mp.set_property_native("pause", true)
	mp.set_property_native("time-pos", 10.000)
	mp.set_property_native("vf", {})
end

function unpause_seek()
	mp.set_property_native("pause", false)
	mp.set_property_native("time-pos", 10.000)
	mp.set_property_native("vf", {})
end

mp.add_forced_key_binding("1", "pause_seek", pause_seek)
mp.add_forced_key_binding("2", "unpause_seek", unpause_seek)
