URL: https://github.com/apache/arrow/issues/43153
### Describe the bug, including details regarding any error messages,
version, and platform.
It looks like `pull(disp)` here is actually getting the data from `gear`.
I've tried this with both released / from CRAN arrow as well as nightlies.
``` r
library(arrow, warn.conflicts = FALSE, quietly = TRUE)
library(dplyr, warn.conflicts = FALSE, quietly = TRUE)
as_arrow <- as_arrow_table(mtcars) |>
group_by(gear, am) |>
pull(disp)
```
``` r
as_arrow
#> [1] 4 4 4 3 3 3 3 4 4 4 4 3 3 3 3 3 3 4 4 4 3 3 3 3 3 4 5 5 5 5 5 4
```
``` r
as_dplyr <-mtcars |>
group_by(gear, am) |>
pull(disp)
as_dplyr
#> [1] 160.0 160.0 108.0 258.0 360.0 225.0 360.0 146.7 140.8 167.6 167.6
275.8
#> [13] 275.8 275.8 472.0 460.0 440.0 78.7 75.7 71.1 120.1 318.0 304.0
350.0
#> [25] 400.0 79.0 120.3 95.1 351.0 145.0 301.0 121.0
```
``` r
as_arrow == as_dplyr
#> [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE
FALSE
#> [13] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE
FALSE
#> [25] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE
```
``` r
setdiff(as_arrow, as_dplyr)
#> [1] 4 3 5
```
**but without grouping**
``` r
as_arrow <- as_arrow_table(mtcars) |>
pull(disp)
as_arrow
#> [1] 160.0 160.0 108.0 258.0 360.0 225.0 360.0 146.7 140.8 167.6 167.6

#> [13] 275.8 275.8 472.0 460.0 440.0 78.7 75.7 71.1 120.1 318.0 304.0
350.0
#> [25] 400.0 79.0 120.3 95.1 351.0 145.0 301.0 121.0
```
``` r
as_dplyr <-mtcars |>
pull(disp)

350.0
#> [25] 400.0 79.0 120.3 95.1 351.0 145.0 301.0 121.0
