Null-Conditional cannot be mixed with indexers

[rezanid]

I noticed that null-conditionals are supported, although I wasn't able to find anything in the docs. But, when combined with indexers they fails. For instance, given the following example.

{{~ for item in a?.b[0] ~}}
  Something
{{~ end ~}}

I receive the following error.

Scriban.Syntax.ScriptRuntimeException: '(1,20) : error : Object a?.b is null. Cannot access indexer: a?.b[0]'

Could it be I'm doing something wrong?

Could you post a small program that replicates this exactly so that I can copy paste it quickly and check what's going wrong? From the error above, it looks like it is b that doesn't have a value, not a, but I can't tell without looking at the whole code.
