A question about theme_xx() and theme()

[Rong-Zh]

library(tidyverse)
platform : Windows 10 x64 build 19045
ggplot2: 3.4.4

the title of the figure is correctly displayed in center with the following code

iris %>% ggplot(aes(Sepal.Width, Petal.Length, color = Species)) +
  geom_point() +
  labs(title = "Test") +
  theme_test() +
  theme(plot.title = element_text(hjust = 0.5))

theme_test() is used after the theme(), the title of the figure incorrectly appears on the left.
the title of the figure should be centered.

iris %>% ggplot(aes(Sepal.Width, Petal.Length, color = Species)) +
  geom_point() +
  labs(title = "Test") +
  theme(plot.title = element_text(hjust = 0.5)) +
  theme_test()

The order of operations matter, so in your second plot, theme_test() is overriding anything you might have declared in theme() before. In any case, this issue tracker is to report bugs or request features. For questions or help, try the community or stackoverflow.
