Viewer shows missing boolean value as if it were False

[6801318d8d]

Describe the bug

The dataframe viewer shows missing boolean values with an unchecked check box like it were a FALSE value

To Reproduce

In the following dataframe, the second vlaue of var2 is missing, but it is shown like it were FALSE

subdf <- structure(list(var1 = c(TRUE, TRUE), var2 = c(FALSE, NA)), row.names = c(NA,
-2L), distance = "distance", weights = "weights", subclass = "subclass", class = c("matchdata",
"tbl_df", "tbl", "data.frame"))
View(subdf)

Can you fix this issue by yourself? (We appreciate the help)

No

Expected behavior

Should clearly distinguish between FALSE and missing
