extract(fun = table) returns only two columns, with matrix in second column

[AramburuMerlos]

When using extract() with fun=table to tabulate raster values for each polygon (and raw=FALSE) I get a data.frame with two columns, in which the second column is a matrix, rather than a data.frame with as many columns as raster classes +1.
See example below

> library(terra)
terra 1.7.46
> 
> f <- system.file("ex/lux.shp", package="terra")
> v <- vect(f)
> z <- rast(v, resolution=.01, names="test")
> values(z) <- as.factor(sample(letters[1:5], ncell(z), replace = TRUE))
> 
> e <- extract(z, v, fun = "table", ID=TRUE, raw = FALSE)
> e
   ID  a  b  c  d  e
1   1 75 73 71 90 80
2   2 62 49 41 65 54
3   3 75 58 60 67 65
4   4 23 20 16 16 20
5   5 80 60 62 51 79
6   6 47 44 46 49 53
7   7 25 30 32 35 36
8   8 51 43 56 64 43
9   9 42 49 43 48 49
10 10 68 67 59 54 62
11 11 54 72 64 55 54
12 12 54 70 50 62 58
> ncol(e)
[1] 2
> class(e[,2])
[1] "matrix" "array"
