rbind() fails when appending tsibbles with yearmonth indices

[mbg-unsw]

---

When I use rbind() to append two tsibbles with yearmonth indices, I get this error:

Error: `levels.yearmonth()` not supported.

e.g.

l1 <- tsibble(t=yearmonth("2020 Jan"), n=1, cat="a", index=t, key=cat)
l2 <- tsibble(t=yearmonth("2020 Jan"), n=1, cat="b", index=t, key=cat)
rbind(l1, l2)

The operation works as expected if the index is a plain date.

Same problem on my end:

x1 <- tsibble::tourism
x2 <- tsibble::tourism

rbind(x1, x2)

Erreur : `levels.yearquarter()` not supported.

What was the reason behind reversing this patch? Somehow this worked for me for at least half a year and started failing after I updated to the current version. Interestingly it errors out somewhere deep inside ggplot. I don't know how it worked before, is it even possible it could've work? Maybe I was casting to tibble somewhere along the process :O

Anyway, why not support binding for tsibbles?

It's not much an issue if all inputs are tsibbles, but I don't think if a tsibble returned by rbind() is always valid. Anyway, the output of rbind() is often unpredictable, if inputs are various data classes. For example, the output can be a matrix. I have kept watching how {tibble} addressed the rbind() issue. And they eventually leave the issue as is ( tidyverse/tibble#909 (comment))
