Stargazer does not recognise tobit even though it is supported

Question

I want to let stargazer print an AER::tobit regression (data at the bottom).

require(AER)
require(stargazer)
s1.tobit <- AER::tobit(taxrate ~ votewon + industry + size + urbanisation + vote,
                  left=12, right=33, data=DF)
stargazer(s1.tobit)

% Error: Unrecognized object type.

According to the vignette this should be no problem: https://cran.r-project.org/web/packages/stargazer/vignettes/stargazer.pdf

Can anyone help me out with what is going on?

Using stargazer v5.2.2 and AER v1.2-9 it works only if you drop the AER:: in front of tobit, which is strange. Maybe you should write a bug-report, although I'd strongly recommend using texreg instead of stargazer.

require(AER)
require(stargazer)
m1.tobit <- AER::tobit(taxrate ~ votewon + industry + size + urbanisation + vote,
                       left=12, right=33, data=DF)
> stargazer(m1.tobit)

% Error: Unrecognized object type.

m2.tobit <- tobit(taxrate ~ votewon + industry + size + urbanisation + vote,
                  left=12, right=33, data=DF)
> stargazer(m2.tobit)
