LinearProblem constructor does not work as intended

**Describe the bug 🐞** The docs suggest that the following should return 1: ```julia julia> LinearProblem(rand(2,2), rand(2), p=1).p SciMLBase.NullParameters() ``` however, the following works at least ```julia julia> LinearProblem(rand(2,2), rand(2), 1).p 1 ``` **Expected behavior** The former should also return 1, according to the docstring ```julia LinearProblem{isinplace}(A,b,p=NullParameters();u0=nothing,kwargs...) LinearProblem(f::AbstractSciMLOperator,b,p=NullParameters();u0=nothing,kwargs...) ``` **Minimal Reproducible Example 👇** Above. **Error & Stacktrace ⚠️** - **Environment (please complete the following information):** - Output of `using Pkg; Pkg.status()` ```julia [0bca4576] SciMLBase v2.134.0 ``` **Additional context** -
