Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The change fixes the stale text-style label, but the editor-wait logic can keep consuming client resources on pages where the editor will never mount, such as unsupported or not-found pages. This is a bounded minor runtime risk that needs owner awareness or follow-up; the PR remains otherwise mergeable. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Stop polling when the editor cannot mount.
If editing is true while hostCanUseEditor() is false, ready is true. PageEditor then returns the host-missing view without mounting WysiwygEditor. Line 46 schedules an animation frame indefinitely. The same condition occurs when load.notFound is true.
Derive the hook input from host support and non-terminal load state.

Summary
The host formatting bar reads the editor once, when it mounts. On a freshly opened page the bar mounts before the editor exists, so its text style menu never sees it: applying a heading works, but the menu keeps showing "Normal text" until you pin/unpin the toolbar or leave edit mode.
The bar now waits for the editor.
useHostEditorexposeseditorReady, and both the pinned and floating bars render once it's true.Ticket Link
