bind_item_handler_registry timing grows each binding

[means0nothing]

Is it normal, that bind_item_handler_registry timing noticeably grows each binding?

import time
import dearpygui.dearpygui as dpg

dpg.create_context()

with dpg.item_handler_registry() as handler:
    dpg.add_item_clicked_handler(dpg.mvMouseButton_Middle)

with dpg.window():
    while True:
        start_time = time.perf_counter()
        for i in range(5000):
            dpg.add_button()
            dpg.bind_item_handler_registry(dpg.last_item(), handler)
        print(time.perf_counter() - start_time)

bind_item_theme timing also grows each binding, and more items exists in dearpygui, the longer it takes
