Please tell me why the .click() method may not work like a real click ?

I write a simple code in chrome in the console:

{let my_let = document.getElementsByClassName("Textinput-Control")[0]; my_let.click();}

"Textinput-Control" - This is the login field on the site (not my site).

When I make a real mouse click on this field, chrome shows a drop-down list of saved logins.

When I do .click() on this field, the drop-down list does not appear, that is, as if there was no click.

Although there is a method on other buttons on this site .click() works. Why can this happen ?

PS: URL site: URL site
