Normally this is fine, but the combination of HMR and dynamic components leads to a bug: Since `svelte-component.js` passes the temporary anchor along to the component it generates, which is the HMR wrapper, this wrapper will have an obsolete, disconnected anchor on updates, leading to the content disappearing. The fix is to add a dev-only symbol which we set on the original (then obsolete) anchor to tell about the updated anchor that should be used for HMR updates.

fix: ensure proper HMR updates for dynamic components (#18079 )

The BranchManager in `branches.js` does create a temporary anchor when
creating a new branch offscreen, and deletes it once the branch is
committed. Normally this is fine, but the combination of HMR and dynamic
components leads to a bug: Since `svelte-component.js` passes the
temporary anchor along to the component it generates, which is the HMR
wrapper, this wrapper will have an obsolete, disconnected anchor on
updates, leading to the content disappearing.

The fix is to add a dev-only symbol which we set on the original (then
obsolete) anchor to tell about the updated anchor that should be used
for HMR updates.
