Description
See attached zip file for reproducible example.
Yesterday I updated my version of Fable to 0.3.1 and shortly after realised that a forecasting script I had been working on had stopped working. I tried the script on both my company laptop (running R v4.0.4) and my personal PC (running R v4.0.5), in both instances I ran into the same problem where running the following line:
cancer_type_rate_fit <- cancer_type_rate_tsib %>%
model(
es = ETS(rate ~ error("A") + trend("A"))
)
caused the R console in RStudio to hang with the small stop sign in the top right. RStudio hung in this state for at least 30 minutes yesterday and remained unresponsive during this time.
Rolling back Fable to version 0.3.0 fixed the issue, so presumably it is a problem with the new release.

Research direction
Start by running the reproducible example in Test.zip with R and Fable 0.3.1, focusing on the model() call using ETS(error("A") + trend("A")). Compare its behavior with Fable 0.3.0 to narrow down the regression. Done means the forecasting call completes without hanging or leaving the R console unresponsive.
