`@mtkmodel` errors when module qualifier is used to create component

[baggepinnen]

The following is fine

using ModelingToolkit
using ModelingToolkitStandardLibrary.Blocks

@mtkmodel TankWithInput begin
    @components begin
        in = Constant(k=308.5)
    end
end

but with the namespace Blocks qualifying the access to Constant, the macro errors

using ModelingToolkit
using ModelingToolkitStandardLibrary.Blocks

@mtkmodel TankWithInput begin
    @components begin
        in = Blocks.Constant(k=308.5)
    end
end

This is still a problem on the latest release of MTK, the following system works fine, but if I use Rotational.Torque instead of the alias RTorque (and similar for BSine) I get the error reproduced below

using Multibody
using ModelingToolkit
using JuliaSimCompiler
using OrdinaryDiffEq
using ModelingToolkitStandardLibrary.Blocks
import ModelingToolkitStandardLibrary.Mechanical.Rotational
@parameters t
D = Differential(t)

# Workarounds for @mtkmodel bugs and limitations
RTorque = Rotational.Torque
BSine = Blocks.Sine
W(args...; kwargs...) = Multibody.world

@mtkmodel ActuatedJoint begin
    @components begin
        world = W()
        torque = RTorque()
        joint = Revolute(useAxisFlange=true) # The axis flange provides an interface to the 1D torque input from ModelingToolkitStandardLibrary.Mechanical.Rotational
        torque_signal = BSine(frequency=1/5)
        body = BodyShape(; m = 1, r_cm = [0.4, 0, 0])
    end
    @equations begin
        connect(world.frame_b, joint.frame_a)
        connect(joint.frame_b, body.frame_a)
        connect(torque_signal.output, torque.tau)
        connect(torque.flange, joint.axis)
    end
end

@named model = ActuatedJoint()
ssys = structural_simplify(IRSystem(model))
prob = ODEProblem(ssys, [D(D(joint.phi)) => 0], (0, 10))
sol = solve(prob, Rodas4())

julia> @mtkmodel ActuatedJoint begin

               torque_signal = Blocks.Sine(frequency=1/5)
               body = BodyShape(; m = 1, r_cm = [0.4, 0, 0])
           end

Ah, I noticed that no release has been made since this fix was merged
