Getting the staccato dot under a repeat tie

[Knute Snortum]

Greetings,

I am trying to get a repeat tie to look more like a slur and I'm having
some trouble getting a staccato dot under a shaped repeat tie.  Here is the
code, and I've attached the output:

%%%
\version "2.24.4"

\relative { \mark A <g' e'\repeatTie>4-. }
\relative {
  \mark B
  <g' e'-\shape #'((0 . 2) (0 . 2) (1 . 2) (1 . 2)) \repeatTie>4-.
}
\relative {
  \mark C
  <g' e'-\shape #'((0 . 1.5) (0 . 1.75) (1 . 1.75) (1 . 1.5)) \repeatTie>4
  -\offset Y-offset -1.5 -.
}
%%%

"A" is the un-tweaked output.  "B" has a \shape changing the repeat tie,
but the dot floats above the tie.  "C" has the shape as I want it and the
dot is manually tweaked into position.

So is there a better way to do this?  Is this a bug in LilyPond?
