Leading space in Checkbox option causes choices to be omitted

[BlairCooper]

Describe the behavior: If an option for a checkbox is proceeded with a space the regular expression for extracting the checkbox choices will omit the option with the leading space and the one before it.

Assume the options for a REDCap checkbox field are set as follows: (note leading space on option 3)

1, Depressive mood disorder
2, Adjustment disorder
 3, Personality disorder
4, Anxiety
0, Not Noted

The resulting value in the "select_choices_or_calculations" field will be as follows: (note the missing space a the end of "Adjustment disorder")

"1, Depressive mood disorder | 2, Adjustment disorder| 3, Personality disorder | 4, Anxiety | 0, Not Noted" (note the missing space a the end of "Adjustment disorder"

Calling checkbox_choices() will only return choices 1, 4 and 0.

Expected behavior: All of the checkbox options are returned from checkbox_choices().

Desktop (please complete the following information):

• OS: Windows 10
• REDCap version 13.7.5
• REDCapR Version 1.1.0

Additional context:
Confirmed this behavior with this test case:

test_that("checkbox choices with errant space", {
  choices_1 <- "1, Depressive mood disorder | 2, Adjustment disorder| 3, Personality disorder | 4, Anxiety | 0, Not Noted"
  ds_boxes <- checkbox_choices(select_choices=choices_1)

  ds_expected <- structure(
    list(
      id = c("1", "4", "0"),
      label = c("Depressive mood disorder", "Anxiety", "Not Noted")
    ),
    class = c("tbl_df", "tbl", "data.frame"),
    row.names = c(NA, -3L)
  )

  expect_equal(ds_boxes, expected=ds_expected, label="The returned data.frame should be correct")
  expect_s3_class(ds_boxes, "tbl")
})
