- Compound 10.3.0 bounds a menu by the space it has and scrolls what
doesn't fit, within a boundary the app passes. The menus pass the call
area, 16px in from its sides, rather than measuring its width.
- The 296px width is the menu's own style. Compound gives that style only
to the dropdown, so menuIsDrawer, which copied its phone rule, goes.
- Compound draws the menu's frame over its content, so nothing that
scrolls can hide it in Safari: the list, headings and meter no longer
keep a border width clear of it, and the checks that they did go.
- The device list is Compound's scroll area, so it fades out at the
foot with Compound's chevron while there is more below.
- The microphone menu's meter sticks at that foot, with rows scrolling
under it as before, so the list has no fade above it: Compound's is a
mask fixed to the list's edge, while a bounce at the top carries the
meter with the rows. The band under the meter is filled, or rows would
show there. The edge fades from where the chevron starts, so a bounce
fades the meter out before it reaches the chevron. A row reached by
keyboard stays above the meter.
- The list's height is still its share of the call.
- The component harness leaves the host's stylesheets unscoped, Compound's
among them, as a host does: scoped, they never reached the menu, which is
portalled out of Element Call's root.
- Its specs check only Element Call's own document styles on the host
page, and find the device list within Compound's scroll area.

With this change, views now read every reactive value through `useBehavior`, as
`architecture.md` already prescribes. Where a view reads a plain stream, the view
model now exposes a `Behavior`.
With the React Compiler, our component code is transformed at build time to automatically apply various forms of memoization. This changes the runtime semantics of our code a little bit and therefore could surface new bugs in the next release cycle in case any components fail to follow the rules of React. See https://react.dev/learn/react-compiler for more information.
This results in a small bundle size increase and modest performance gains, but I think it's worth it given the potential for larger performance gains once we tune the component structure a bit more.
