kableExtra: short.caption argument not working if creating table from list or using list of dataframes

问题

The goal is to include a kableExtra table in a PDF/HTML report generated with Rmarkdown/bookdown. The short.caption argument allows displaying a shortened version of the caption in the list of tables.

When generating a kableExtra table from a list or a list of dataframes, the short.caption argument does not function anymore. The long caption is shown in the list of tables of the PDF report. Also, using markdown expressions like **BOLD** do not work in the titles either.

```{r CHUNK, echo=FALSE}
library(kableExtra)
my_list <- list(left = c(68, 48, 50, 113, 98, 94),
     right = t2 <- c(26, 16, 22, 30, 16, 12))

kable(
  my_list, 
  caption = "**Complete caption** for main document",
  caption.short =  "Short caption for LoT" 
)
```
