This is intentional. You can switch it off using

\version "2.22.1"

\new Voice {
  $(add-grace-property 'Voice 'Stem 'no-stem-extend '())
  \stemUp \grace g,8-. g,4
}

Note that creating the voice explicitly with
\new Voice is important here. Please see

Perhaps, but this becomes hardly feasible when you
consider

\version "2.22.1"

<<
  { e' }
  \\
  { \stemDown g,\tweak Y-offset -1.5-. }
>>

The script position should normally be below the
note, not above it. That happens automatically
if you use \voiceTwo rather than the very specific
\stemDown.

Could you give an example where this happens?
