This removes the tooltip due to being zero or negative information, and
also changes the description of the setting to not contain the word
"mirror", which will hopefully quash the "this is where I would place a
mirror to my screen to achieve what I want" interpretation which seems
to be a minority interpretation.
The first time this was complained about I figured this was probably a
one guy issue, but now it's happened twice, and I never want to see this
conversation again.
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.
