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.
