Screen screenshots show in Chrome, Edge, and Brave

In Chrome, Edge, Brave, and other browsers built on Chromium, a screen's screenshot had stopped showing, both in the Screenshot card on the screen's Overview tab and as the screen's preview in the Screens list. Firefox still showed it. New screenshots load in every browser.

A screenshot taken before this release can still fail to load until the screen replaces it. A screen that's online sends a new one about every 15 minutes, and old screenshots are removed after a day. To get a new one right away, press "Take screenshot" on the Overview tab of a screen that's online, the button that came with screenshots on demand.
