Bug: SVector(SVector(x))===SVector(x)

[PhilippeMaincon]

Constructing a length=1 SVector, with element a length=1 SVector results in one container being peeled away.

SVector(SVector(x))===SVector(x) forall x...

eltype(SVector(SVector(:a))) returns Symbol

SVector{1,SVector{1,Int64}}(SVector(1))
ERROR: MethodError: Cannot `convert` an object of type Int64 to an object of type SVector{1, Int64}

That's with StaticArrays v1.9.16, but also StaticArrays v1.9.18

I found a workaround
SVector{1}(SVector(:a) for i = 1:1)
or
SVector{1,SVector{1,Symbol}}(SVector(:a) for i = 1:1)
