Closes https://github.com/ppy/osu/issues/30237.
This is the root failure in the issue, and one that *only* presents when
another conversion mod that repositions the objects is also active. That
makes the `PathProgress` of the nesteds to be zero, therefore making
them occupy the position of the slider head after any mutation to the
path.
Closes https://github.com/ppy/osu/issues/25816.
Regressed in https://github.com/ppy/osu/pull/25748.
The reason this broke is that allowing the state of `Tracking` to change
before the slider's start time to support the early hit scenario causes
strict tracking to consider loss of tracking before the slider's start
time as an actual miss, and thus forcefully miss the tail
(see test case in 6cb8231054).
