Fails to load a Table grammar inside a paragraph

[csMACnz]

It caused errors when adding the paragraph grammar, then once added and saved, it causes catastrophic failure (see stacktrace below)

I have one IGrammar method using Paragraph with x += this["TableMethod"].
I have the TableMethod IGrammar using either this["Item"].AsTable("Table") or using CreateNewObject(...).AsTable("Table"). Both fail with this issue.

Tested with various recent versions, still fails with Storyteller Version=4.3.1 and dotnet-storyteller Version=1.1.2

 TypeError: this.children[0].selectFirst is not a function

(Possibly related to #415)

hmmm, i may have been seeing two instances of the same bug in two places.
I suggest investigation around CreateNewObject inside a Grammar, used inside a paragraph potentially causing the above. It looks from above that the this is the grammar, inside the paragraph, but the this.children[0] is the silent grammar from _.ObjectIs = c => new T(); inside CreateNewObject (

Storyteller/src/StoryTeller/Fixture.cs

Line 399 in 84cc8e5

_.ObjectIs = c => new T();

)

My workaround for now is avoid CreateNewObject and set up CurrentObject management seperately.
