axis_titles = "collect" does not work when modifying panel grid

For example when adding theme(panel.grid.major.x = element_blank())

Could you provide a reproducible example? I tried to replicate your issue, but I wasn't able to do so. In the simple example below, for example, the axis titles are still collected even after the grid lines have been removed from one plot.

library(ggplot2)
library(patchwork)

packageVersion("ggplot2")
#> [1] '4.0.1'
packageVersion("patchwork")
#> [1] '1.3.2'

p1 <- ggplot(mtcars) +
  geom_bar(aes(gear)) +
  theme(panel.grid.major.x = element_blank())

p2 <- ggplot(mtcars) +
  geom_boxplot(aes(gear, disp, group = gear))

p1 + p2 +
  plot_layout(axis_titles = "collect")

Your example indeed works. I can't quite figure out why in my code it is not working. I will keep trying to make a reproducible example.
