[Bug] Struct-typed pattern-local variables behave unexpectedly

What's the issue you encountered?

When a struct is used for a pattern-local variable, all fields of the struct appear to have the value of the first field.

How can the issue be reproduced?

Create a new file (or open a random one, doesn't matter) and execute the following pattern:

import std.io;

struct Test
{
    u32 a;
    u32 b;
};

fn get_test()
{
    Test ret;
    ret.a = 100;
    ret.b = 200;
    std::print("get_test returning {}, {}", ret.a, ret.b); // Always prints 100, 200 as expected
    return ret;
};

Test t = get_test();
std::print("Global variable: {}, {}", t.a, t.b); // Prints 100, 200 as expected

struct Pattern
{
    Test tt = get_test();
    std::print("Pattern local variable: {}, {}", tt.a, tt.b); // Prints 100, 100, which is not expected
};

Pattern p @ 0;

Expected behavior: All printed messages say 100, 200

Actual behavior: The pattern-local variable test prints 100, 100
