column formatters cannot be used when rowname_col includes hyperlinks

[jdjohn215]

Description

Thanks for the great package. I recently realized that when the table stub includes hyperlinks, using a column formatting function elsewhere in the table returns this error: Error in vars_validate(): ! vars must be a character vector.

Reproducible example

Here's a table with a markdown link in the name column.

df <- tibble(
  name = c("[BBC](https://www.bbc.com/news)", "[CNN](https://edition.cnn.com)"),
  country = c("UK", "US"),
  pct = c(0.75, 0.25))

This works:

df |>
  mutate(name = map(name, gt::md)) |>
  gt() |>
  fmt_percent(columns = pct)

So does this:

df |>
  mutate(name = map(name, gt::md)) |>
  gt(rowname_col = "name")

But this gives an error:

df |>
  mutate(name = map(name, gt::md)) |>
  gt(rowname_col = "name") |>
  fmt_percent(columns = pct)

Here's my session info. Thanks!
