### Godot version

4.0.beta16

### System information

windows 10

### Issue description

whenever an animation starts playing and there is an animation track in it with at least one key, the seemingly innocuous error message gets printed:
```
ERROR: Condition "!playback.current.from" is true.
   at: seek (scene/animation/animation_player.cpp:1784)
```
It apparently doesn't cause any kind of erroneous behavior, and the other animation player seems to play the animation as expected.

### Steps to reproduce

### Work Around

Instead of using animation playback tracks, the user can use method call tracks and call the play method in the desired animation player
double delta = p_delta * speed_scale * cd.speed_scale;
	double next_pos = cd.pos + delta;
	bool backwards = signbit(delta); 
	real_t len = cd.from->animation->get_length();
	Animation::LoopedFlag looped_flag = Animation::LOOPED_FLAG_NONE;
	switch (cd.from->animation->get_loop_mode()) {
		case Animation::LOOP_NONE: {
			if (next_pos < 0) {
				next_pos = 0;
			} else if (next_pos > len) {
				next_pos = len;
			}
			delta = next_pos - cd.pos; 
		} break;
		case Animation::LOOP_LINEAR: {
			if (next_pos < 0 && cd.pos >= 0) {
				looped_flag = Animation::LOOPED_FLAG_START;
			}
			if (next_pos > len && cd.pos <= len) {
				looped_flag = Animation::LOOPED_FLAG_END;
			}
			next_pos = Math::fposmod(next_pos, (double)len);
		} break;
		case Animation::LOOP_PINGPONG: {
			if (next_pos < 0 && cd.pos >= 0) {
				cd.speed_scale *= -1.0;
				looped_flag = Animation::LOOPED_FLAG_START;
			}
			if (next_pos > len && cd.pos <= len) {
