Multicolumn Footnote with kableExtra on Quarto document

I have a table generated with kableExtra with a footnote that spans over several columns. If I run it separately in R it displays properly. However, when run inside a Quarto document, it constraints the text of the footnote to the width of the 1st column.

Here is a reproducible example

library(kableExtra)dt <- mtcars[1:5, 1:4]# HTML tablekbl(dt, caption = "Demo Table") %>%  kable_styling(bootstrap_options = "striped",                full_width = F) %>%  add_header_above(c(" ", "Group 1" = 2, "Group 2[note]" = 2)) %>%  footnote(c("Let's make a very long table footnote"))

Has any one experienced this before, and if so knows how to fix it?
