Resolve the pre-merge review items for the #146 NodeView content-first fix:
- Export collectScrollAncestors/reflowAfterPaste and add editor-paste-handler
unit tests covering ancestor selection (overlay included, non-overflowing
auto excluded, X axis), the scrollHeight>clientHeight gate, scrollingElement
dedup, the docEl==null branch, and the double-rAF nudge.
- Extend the structural guard with CodeBlockView and merge the two it.each
blocks into one document-order assertion (handles the <pre> nesting where the
contentDOM is not the literal first child).
- Simplify the post-paste nudge to a single scrollTo(scrollLeft, scrollTop).
- Document that the post-paste reflow runs on every paste path intentionally,
and cross-reference the two #146 mitigations in both fixes.
- a11y: aria-hidden the decorative footnotes heading and number marker, and
label the footnotes list via role="group" + aria-label so the visual reorder
does not break screen-reader reading order (WCAG 1.3.2).
- CHANGELOG: add a Fixed entry noting the caret fix is macOS-verified manually.

Addresses the #147 review (Approve with comments):
- Add footnote-views.structure.test.tsx: a structural regression guard asserting
the editable NodeViewContent is the FIRST child of FootnotesListView and
FootnoteDefinitionView, with no contenteditable=false chrome before it. The
whole #146 fix rests on this DOM-order invariant; the macOS caret symptom needs
a real browser, but the order proxy is testable in jsdom. Stubs @tiptap/react
so the views render as plain DOM — the test passes on the fixed order and fails
on the pre-fix chrome-first order.
- Reword the code-block-view comment: it claimed a "top-right overlay (the
transclusion pattern)", but the menu stays fully in flow as a full-width row
lifted via flex `order: -1` (the .codeBlock wrapper is a flex column). No
overlay/absolute positioning.

Pasting markdown/code inserts React NodeViews that mount asynchronously; until
the next reflow the browser's hit-test geometry is stale, so ProseMirror's
posAtCoords/caretRangeFromPoint maps a click to the wrong (offset) line — which
users reported clears itself on any scroll. Reproduce that scroll's side effect
with a ZERO-delta nudge (re-assign scrollTop/scrollLeft to their current value)
on every scrollable ancestor + the document scrolling element, run across two
animation frames so it lands after the pasted content + NodeViews commit. The
nudge does not move the viewport.
Wired into editor-paste-handler's handlePaste, which ProseMirror's someProp runs
(as an editorProps handler) before the MarkdownClipboard plugin that performs the
markdown/code insert — so the nudge is scheduled on exactly the paste path that
triggers the bug. Complements the structural NodeViewContent-order fix in this
branch.

Three editable NodeViews rendered a contentEditable=false "chrome" element IN
FLOW BEFORE NodeViewContent. On macOS the browser's click hit-testing
(posAtCoords → caretRangeFromPoint) then misses the contentDOM and snaps the
caret to the previous node — the caret/selection lands a line (code block) or
several lines (footnotes, into the body) above where the user clicked.
Fix (the transclusion pattern / issue #146 plan): make the editable
NodeViewContent the FIRST child in the DOM and move the non-editable chrome
AFTER it, restoring its visual position with CSS:
- code-block-view: <pre><NodeViewContent/></pre> first; the language/copy menu
follows and is lifted above via flex `order` (.codeBlock is now a flex column).
- footnotes-list-view: NodeViewContent first; the "Footnotes" heading follows and
is lifted above via flex `order` (.list is a flex column; the separator border
stays on the container).
- footnote-definition-view: NodeViewContent first; the "N." marker follows with
`order:-1` to stay on the left; the ↩ back-link stays on the right.
Layout is visually unchanged. Verified in a real browser (Chromium): the
contentDOM is now the first child of every editable NodeView wrapper (no
contentEditable=false element precedes it), and the menu/heading/marker still
render in their original positions.
NOTE: the caret-offset itself is macOS-specific text hit-testing and does not
reproduce in headless Chromium/WebKit on Linux (verified extensively), so the
visible fix is best confirmed on macOS.
