Toolbar deletion removes an entire selected section, but the keyboard shortcut deletes only its heading and leaves orphaned paragraphs. The two handlers also record different undo entries.

Pattern topics
Undo restores paragraph text but leaves the caret pointing to the deleted node identity. A second edit then modifies the wrong paragraph. History currently keeps an editable reference to the live tree.

Pattern topics
Opening and closing the preview panel twenty times makes one edit trigger twenty-one outline refreshes. Subscriptions remain in the document store after the panel unmounts.
Estimated field mix
Pattern topics
Selecting a link makes the toolbar call the inspector, the inspector call the outline, and the outline call the toolbar again. A new panel added another circular dependency and occasional repeated selection updates.
Estimated field mix
Pattern topics
Import sets isLoading but leaves isEditable true. A user types while the asynchronous parser runs, then the parsed document replaces those edits without a warning.
Estimated field mix
Pattern topics
A generated 20,000-paragraph fixture repeats twelve formatting combinations. A proposed style pool reduces duplicate objects, but its mutable shared entries can change many paragraphs when one is edited.
Estimated field mix
Pattern topics
Every new export format adds another method to paragraph and section objects. The team needs plain text and a structured outline, and expects document node types to change less often than export formats.
Estimated field mix
Pattern topics
A delayed keyboard event queues Undo just before a successful import installs another document. The old history entry then restores part of the previous document into the replacement because both documents happen to contain node p1.
Estimated field mix
Pattern topics
Provider A returns accepted plus a request ID; provider B returns queued with a nested reference. The existing mapper calls both delivered, even though neither acknowledgement confirms a recipient received the notice.
Estimated field mix
Pattern topics
Rescheduling logic imports provider B's request object and recognizes its numeric error codes. A provider SDK change now forces changes in domain tests that never make a network request.
Estimated field mix
Pattern topics
An invalid synthetic recipient passes provider selection and fails differently for A and B. Another path checks the notification preference only after the stub has already accepted the request.
Estimated field mix
Pattern topics
ReminderEmailProviderA and CancellationEmailProviderA have matching ProviderB subclasses. Adding a third notice type is multiplying classes even though formatting and transport are independent choices.
