Reproducible example

gt::exibble |> 
  gt::gt() |> 
  gt::tab_footnote("first footnote", locations = gt::cells_column_labels(char)) |> 
  gt::tab_footnote("second footnote on second line", locations = gt::cells_column_labels(time)) |> 
  gt::opt_interactive()

As you can see, the second footnote is on the same line.

I dont see this behavior in static html

Expected result

1 footnote per line.
