No form on this page. Clicking below opens the real login form in a new browser window.
The main page shows only a Log In button; there is no form and no username or password field anywhere in this document. Clicking the button calls window.open() to launch a separate, smaller browser window that holds the real form. Tests whether a content script’s capture logic, generally scoped to the tab and document it was injected into, follows a login into a window opened this way, as distinct from an iframe or an ordinary navigation within the same tab.
Check it in DevTools: Elements panel on the main page: there is no form anywhere, only a button whose onclick calls window.open(...). Switch to the new window and open DevTools there separately; the real form, with its own username and password inputs, lives in that second document, not this one.
