Failure to reach fixpoint with align_matrix=true

[kbarros]

The input:

using JuliaFormatter
str = """f([a b
            c d])
         """
format_text(str; style=SciMLStyle(), align_matrix=true)

gives the error:

ERROR: formatted_text hasn't reached to a fixpoint in 4 iterations
Stacktrace:

It works, however, with style = BlueStyle().

this is because sciml mixes styles at the pretty and nesting stages which it should not do. nesting functions assume the tree was prettified with the same style. so in this case the pretty function uses YAS but then the nest uses Default. If you want this to work turn on yas_style_nesting=true but it might provide other formats you don't want

I was exploring the various possible formatting options, but am not particularly attached to this combination. If sciml style is incompatible with align_*, then perhaps print an error at the level of the call to format_*() to indicate lack of support?
