kableExtra rmarkdown tables - aligning grouping row labels and footnotes

I am using kableExtra to format some tables in an Rmarkdown document. When running the code below, without any position argument to kable_styling, the grouping row labels (the rows in the table where it says "Group 1" and "Group 2") and the footnotes remain left aligned in relation to the table. This is as I would like it.

```{r cars-table, results='asis'}
kable(mtcars[1:10, 1:2], format = "html", caption = "Group Rows", 
     col.names = c("MPG[note]", "CYL[note]")) %>%
kable_styling("striped", full_width = F) %>%
group_rows("Group 1", 4, 7) %>%
group_rows("Group 2", 8, 10) %>% 
add_footnote(c("Some footnote", "Some other footnote"))
```

kableExtra_workingtable

But when a position argument is provided to kable_styling, the grouping row labels and footnotes seem to take the opposite alignment, rather than remaining left aligned in relation to the table. I say the opposite alignment, as when I use position = "right", the grouping row labels and footnotes become left aligned.

The code below demonstrates the issue when using position = "left".

```{r cars-table, results='asis'}
kable(mtcars[1:10, 1:2], format = "html", caption = "Group Rows", 
     col.names = c("MPG[note]", "CYL[note]")) %>%
kable_styling("striped", full_width = F, position = "left") %>%
group_rows("Group 1", 4, 7) %>%
group_rows("Group 2", 8, 10) %>% 
add_footnote(c("Some footnote", "Some other footnote"))
```

kableExtra_notworkingtable

I only load two libraries to make this example and use the defaults when opening an .Rmd document in RStudio.

library(knitr)
library(kableExtra)

What can I do to make the grouping row labels and footnotes left aligned in relation to the table? Thanks.

In kableExtra 0.3.0 or earlier, there was a bug in the position section of kable_styling. The corresponding CSS for left positioning was mistakenly set as text-align:right... Thank you, @meenaparam, for bringing it up!

Now this bug has been addressed in the current dev version and the CRAN version will be updated in a week.
