[Bug] Passing a (placed) struct as non-type template parameter makes it disappear

What's the issue you encountered?

When passing structs that have been placed as non-type template parameter, they no longer render in the hex-edoitor or pattern data. This doesn't happen with built in types (like u32), but it does with structs.

How can the issue be reproduced?

struct A {
    u8 field1;
};

struct B<auto S> {
    u8 arr[S.field1];
};

A a @ 0x00;
B<a> b @ 0x01;

a doesn't get rendered.

struct B<auto S> {
    u8 arr[S.field1];
};

u32 a @ 0x00;
B<a> b @ 0x01;

a gets rendered.

This looks a lot like #1628. Maybe they are related.

This looks a lot like #1628. Maybe they are related.

Seems to be the case.

If I do instead:

struct A {
    u8 field1;
};

struct B<auto S> {
    u8 arr[S];
};

A a @ 0x00;
B<a.field1> b @ 0x01;

neither a, nor a.field1 disappears.

By doing:

struct C {
    u8 field2;
};

struct A {
    u8 field1;
    C fieldC;
};

struct B<auto S> {
    u8 arr[S.field2];
};

A a @ 0x00;
B<a.fieldC> b @ 0x02;

a.fieldC disappears but a.field1 doesn't, like in that issue.
