About data copy，the data is in custom section

[xyjdwxzxxbw]

Hi，
when i was running this test case，
zephyr\tests\application_development\code_relocation
I noticed this phenomenon:
__in_section(custom_section, static, var) uint32_t var_custom_data = 1U;
The initial value of this global variable should be 1，and the console print its address
Address of custom_section data placed using attributes 0x809ba8
but when i see the address，the value is not 1：

I looked at the initialization process of zephyr. When a variable is placed in a custom section, zephyr does not copy it. Does this cause the initial value of the variable to be lost?

in zephyr\kernel\xip.c
void z_data_copy(void),this function do the data copy work,
Or maybe is there another place where the copying has been done that I don't see?
