'AsIs' position invalid when setting coord_sf: 'default_crs' parameter

[Breeze-Hu]

The problem stems from an annotation about adding an out-of-panel position annotate. https://stackoverflow.com/questions/79222655/ggplot2-adds-a-second-image-title-on-the-right-side It has been suggested that ggplot 3.5.0 provides a more convenient location setup : ‘AsIs’ position aesthetics I() . However, when mapping using coords_sf, there are some problems: everything works fine without asserting default_crs in it. Once this parameter is supplied, the labeled position changes. It should go back to using the x,y axis coordinates as defined.

library(tidyverse)
library(sf)
library(rnaturalearth)
ne_countries(continent = "africa") |> 
  # st_crs()
  ggplot()+
  geom_sf()+
  ggtitle('left')+
  annotate("text", label = "right", x = I(1), y = I(1), hjust = 1,
           vjust = -1, size = 4) +
  coord_sf(crs ="+proj=laea +y_0=0 +lon_0=155 +lat_0=-90 +ellps=WGS84 +no_defs",
           # default_crs = st_crs(4326),
           clip = "off")

Expected results:

library(tidyverse)
library(sf)
library(rnaturalearth)
ne_countries(continent = "africa") |> 
  # st_crs()
  ggplot()+
  geom_sf()+
  ggtitle('left')+
  annotate("text", label = "right", x = I(1), y = I(1), hjust = 1,
           vjust = -1, size = 4) +
  coord_sf(crs ="+proj=laea +y_0=0 +lon_0=155 +lat_0=-90 +ellps=WGS84 +no_defs",
           default_crs = st_crs(4326),
           clip = "off")

The position of the labeling has changed and seems to follow the definition of the axes:

I think the current expectation is that AsIs works only with cartesian coordinates. This probably requires some new mechanism like the one proposed in #5609. But, probably this needs to be noted on some documentation at least.

I'm fine with adhering to npc coordinates when x and y are both 'AsIs' variables. I'm unsure what the 'principle of least surprise'-outcome would be when only one of x/y is an 'AsIs' variable, and the other is a regular coordinate.
