I just updated my R-Version from 4.2.2 to 4.4.1. After updating I needed to install some new packages. However, now the borders of my rendered tables are not connected anymore. Do I need to install or update something else?

Here is a code example:

library(kableExtra)
library(magrittr)

df <- data.frame(
  Name = c("Alex", "Bernd"),
  Nummer = c(1,2)
)

kable(df) %>% 
  kable_styling(latex_options = "HOLD_position") %>% 
  column_spec(1, border_left = TRUE) %>% 
  column_spec(2, border_right = TRUE)

and this is what I get with my 4.2.2 version:

connected borders

and this is what I get with my 4.4.1 version:

unconnected borders

Can someone help me, what is missing?
