timerange for fx variables

[rebeccaherman1]

ESMValTool appears to be able to expand timerange: '*' and timerange: '*/*' for variables that vary over time, but not for fx variables like areacella and areacello.
If I try to use an area statistic, areacella or -o is required, and it is brought in as a supplementary variable whether I do it explicitly or not. But when I've used wildcard expansion for the main variable, it ends up giving me the following:
ignoring supplementary variable 'areacello', unable to expand wildcards 'time_range'.
My only idea is to overwrite "timerange" for the supplementary variables, but I have no idea what to replace it with for fx variables.
Please help!

(I am somewhat perplexed that the algorithm is complaining about "time_range", with "_", rather than "timerange", which is the name of the facet that works...)

Hi @rebeccaherman1 cheers for the sight of this! This wafts like a bug - time_range is an internal supplementary_ds.facets['short_name'] but time range/timerange should never be checked on the fx datasets, could you please post a very minimal recipe that I can use to reproduce the issue? Also, am escalting the discussion item to an issue in ESMValCore 🍺
