Bug Summary and Steps to Reproduce

Bug Summary:

The InteliSense output doesn't pars consteval correctly. Mose hover-over doesn't work for values of a struct returned by consteval.

Steps to reproduce:

#include <array>
#include <cstddef>
#include <cstdint>
#include <string_view>

namespace demo {

struct Register_t {
    std::string_view name;
    std::int64_t address;
};

inline constexpr auto registers = std::array{
    Register_t{"register_name", 0x1000},
};

template <std::size_t N>
consteval const Register_t& find_register(std::string_view name, const std::array<Register_t, N>& regs) {
    for (const auto& reg : regs) {
        if (reg.name == name) {
            return reg;
        }
    }
    throw "Register not found";
}

consteval const Register_t& get_register(std::string_view name) { return find_register(name, registers); }

}  // namespace demo

static constexpr std::int64_t register_address = demo::get_register("register_name").address;

static_assert(demo::get_register("register_name").address == 0x1000);
static_assert(register_address == 0x1000);

The mouse hover-over of demo::get_register("register_name").address just return int64_t demo::Register_t::address instead of the expected value 0x1000 as it is done through the assigned value in register_address

Expected behavior:

Mouse hover-over on demo::get_register("register_name").address shows also the value.

It seems that the behavior isn't that stable, means that some times the value is returned and sometimes not. e.g. in Version 1.29.3 the values are shown when it is used for template initialization.
