Reported: closing the keyboard on purpose, while a reply was streaming, left the composer floating above the bottom of the screen for the rest of the session -- a bar of background colour under it, nothing that closed it. The composer's position and the transcript's bottom padding are both driven by the raw, animated `WindowInsets.ime` value, read inside a `graphicsLayer` block specifically so a keyboard frame invalidates layer properties only rather than recomposing the whole screen (see the layout note above it). That value is carried by a `WindowInsetsAnimationCallback`, and a callback interrupted mid-flight leaves whatever it was carrying frozen at its last value with nothing left to correct it -- no further keyboard movement is coming to fire the callback again. A streaming reply invalidates the view every frame, which is exactly the condition known to starve a running callback of its `onEnd`, and that is the "actively responding sessions" correlate in the report. `WindowInsets.isImeVisible` doesn't share that failure mode: it is set once, from the platform's own start/end of the transition, over a different path (`onApplyWindowInsets` rather than the animation callback) -- so it cannot get stuck mid-animation the way the interpolated value can. Read once per keyboard toggle and used to force both the composer's translation and the transcript's reserved padding back to exactly zero the moment the platform says the keyboard is gone, whatever the animated value still claims. Checked on the emulator with an actively streaming echo session: opened the keyboard, closed it with the system back gesture while the reply kept growing, and the composer settled flush at the bottom with the transcript filling the freed space, both immediately and after the keyboard was reopened and closed again.
