Footnote marker appears in new line if formatted with Markdown

[turbanisch]

With default formatting, the footnote marker appears right after the cell content:

library(tidyverse)
library(gt)

table <- mtcars %>% 
  head(5) %>% 
  select(1:3) %>% 
  gt() %>% 
  tab_footnote(footnote = "A footnote.", 
               locations = cells_body(1, 3)) 

table

If the column where the footnote marker appears is formatted using Markdown, however, the marker appears on a new line:

table %>% 
  fmt_markdown(columns = 1)
