caption trimmed when using minor sign (<)

[mafed]

Description
When using the minor sign < in a kable caption kable_styling() cuts off everything after that symbol. Is there a way to avoid it?

To Reproduce

library(knitr)
library(kableExtra)
library(stringr)

example <- mtcars %>% 
  head(n = 3) %>% 
  kable(caption = paste0("Caption trimmed when ",
                         "using the minor sign. ",
                         "After this sentence nothing printed. ",
                         "< 'other text', `verb text`")) 
## kable preserves caption in HTML format
str_sub(example, end = 200) %>% 
  cat()
## kable_styling removes everything after the minor sign
example %>% 
  kable_styling()

You might want to escape that < with \\<.

Thanks for the quick reply @haozhu233 but it doesn't work (I tried that already).
Curiously, the greater sign > is kept as verbatim by kable() and then correctly converted to > by kable_styling().
To me this suggests there is an automatic caption parsing but doesn't check for < (but checks for >).

I see. Are we talking about html or latex?
