adding a theme to gt object inflates output html file size unreasonably

[salupere]

Description

When using gt_theme function inside quarto/rmardown html knitted document, adding theme to each table increases final html file size about 7 megabytes. Without theme the below example woul be around 1 MB, theme adds 7MB. Therefore longer reports (with tens of tables) would be rendered unportable.

Reproducible example

library(dplyr)
#> 
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#> 
#>     filter, lag
#> The following objects are masked from 'package:base':
#> 
#>     intersect, setdiff, setequal, union
library(gt)
library(gtExtras)

tibble(
  Column1 = c(1, 2, 3, 4, 5),
  Column2 = c('A', 'B', 'C', 'D', 'E'),
  Column3 = c(TRUE, FALSE, TRUE, FALSE, TRUE)) %>% 
gt() %>% 
gt_theme_nytimes()
