|> vs %>% Why does one work but not the other?

General

I have been happily using the |> version of pipes since it was made a part of "base" r. However, I just encountered a situation where it did not work and I had to revert back to the %>% pipe code. I don't know why one would work and one wouldn't and I'm curious how I am properly supposed to pass a dataframe to ggplot within pipes.

Code that DIDN'T work:

dataframe |> ggplot( aes(x = x_variable, y = y_variable) ) + geom_col(data = . |> filter(y_variable >= 0), fill = "red") + geom_col(data = . |> filter(y_variable <= 0), fill = "blue")

Code that DID work:
dataframe |> ggplot( aes(x = x_variable, y = y_variable) ) + geom_col(data = . %>% filter(y_variable >= 0), fill = "red") + geom_col(data = . %>% filter(y_variable <= 0), fill = "blue")

There are several differences between the inner workings of |> and %>%, as described here (in particular, %>% is more flexible), and it looks like you're running into one of them.
