On mount ConnectedRoot immediately reported the iframe height to the parent page while the app was still showing the global preloader, so the parent shrank the iframe from its initial size to ~63px and then grew it back step by step as content rendered. On pages with many comments this reads as the widget blinking several times before loading (reported for radio-t.com). The June frontend dependency refresh (#2091) shifted render/effect timing enough to make the premature measurement happen on every load rather than only on slow connections. Move the height reporting into Root and start it in the setState callback that replaces the preloader with real content: the first height message now always describes rendered content, the iframe never shrinks below it, and subsequent ResizeObserver updates only grow the frame as comments arrive. Also adds the previously missing observer disconnect on unmount. Verified by instrumenting the embed with a height-message listener: master sent 63px then 316px on an empty test page (v1.16.1 sent a single 316px); with this fix the first message is 316px again.
