Remove labels in facets not working with element_markdown axis

[Ari04T]

Hello

First of all, thanks for the great package. You've added a ton of great extra functionality to ggplot2.

I want to report what seems like a bug to me. If I create a chart the following way, everything works properly

mtcars %>% 
    ggplot(aes(as.factor(cyl), mpg)) +
    geom_point() +
    facet_wrap2(~ cyl,  axes = "all", remove_labels = "x", ncol = 1)

But if I change the x-axis type to element_markdown, I get the following chart

mtcars %>% 
    ggplot(aes(as.factor(cyl), mpg)) +
    geom_point() +
    facet_wrap2(~ cyl,  axes = "all", remove_labels = "x", ncol = 1) +
    theme(
        axis.text.x = element_markdown()
    )

As you can see, facet_wrap2 with the remove_labels parameter doesn't remove the x-axis labels when they are specified as a markdown element.

Ah yes this does seem like an oversight on my end, thanks for reporting it! It seems fixable (specifically for the element_markdown case, don't know about others), but I can't tell you exactly when I might find the time to fix this.

Should now work for rich text grobs as well, on dev version:

library(ggplot2)
library(ggh4x)
library(ggtext)

ggplot(mtcars, aes(as.factor(cyl), mpg)) +
  geom_point() +
  facet_wrap2(~ cyl, axes = "all", remove_labels = "x", ncol = 1) +
  theme(
    axis.text.x = element_markdown()
  )
