Why in 'headless' browser mode does Selenium not click on the button?

Question

Python

Hello.
Maybe someone came across why in the 'headless' mode Selenium does not click on the button, or clicks somehow "virtually" (in fact, there is no click).
That is, if I write code like this:

browser.find_element_by_class_name('posting_submit.button-pro').click()

then in normal browser mode the button is pressed. In 'haedless' mode I get the error selenium.common.exceptions.ElementClickInterceptedException: Message: element click intercepted
If I write code like this:

share = browser.find_element_by_class_name('posting_submit.button-pro')
browser.execute_script("arguments[0].click();", share)

or like this:

share = browser.find_element_by_class_name('posting_submit.button-pro')
webdriver.ActionChains(browser).move_to_element(share).click(share).perform()

then the button is pressed in both modes, but, in 'headless' mode, it is allegedly pressed - it is not actually pressed (the rest of the code falls).
Who can faced similar? How can this be overcome?

Answer 1

do not use for haedless browser.maximize_window()
use specific size--window-size=1200,600
