grid.ls only shows the top-level layout

I want to use gridSVG::grid.garnish to add information to SVGs I export from ggplot2, but it only works on one grob at a time—that is to say, you need to know which grob is which. I understanding that I can use grid.ls to identify the structure of grobs in a plot, but when I call grid.ls myself, it only shows the top-level layout:

library(tidyverse)
library(gridSVG)

p1 = quickplot(1:5, (1:5)^2)
p1g = ggplotGrob(p1)
grid.ls(p1g)
# layout

I've tried using different arguments (like recursive = TRUE and fullNames = TRUE), and also a variety of different ggplot-based plots, but I invariably only get the top-level layout (or, with fullNames = TRUE, gtable[layout]). How can I see the child grobs?

I'm using ggplot2 v. 2.2.1.9000 and gridSVG v. 1.6-0 on macOS.

Use grid.force ("Some grobs only generate their content to draw at drawing time; this function replaces such grobs with their at-drawing-time content."):

grid.ls(grid.force(p1g))
