react-v1.11.0

What's New

• Textbox content editing — Click to edit text inside textboxes in body, headers, footers, and table cells with full selection and caret support.
• Zoom modes and fit-width — Choose zoom mode (manual or fit-width for auto-fit) and read state, calculations, bounds, and viewport metrics from ui.zoom.
• Viewport change events — Listen for viewport-change when the container resizes to receive document width, available width, and calculated fit-zoom.
• Font family combobox — Search for fonts in the toolbar by name and see per-document options with substitution evidence.
• Comments activation API — Highlight comments without scrolling using ui.comments.setActive(), and access the captured selection from pending comment events.
• Text range viewport rects — Pass Document API text targets to ui.viewport.getRect() to get painted rects for overlay positioning.
• Scroll container access — Call ui.viewport.getScrollContainer() to find the element that actually scrolls, or null for window scroll.
• Sidebar geometry updates — ui.viewport.observe fires when the comments rail opens or closes.
• TOC interactions — Hover highlights sections in the table of contents, and click navigates to them.

Improvements

• Column balancing — Multi-column sections balance at continuous section breaks, matching Word's behavior.
• Grouped tracked changes — Inline cell changes inside a whole-table tracked change now group as one review item.
• Line break serialization — Newlines in text mutations serialize as <w:br/> and round-trip without loss.
• Tab and soft-break carets — Tab carets anchor to line top, and soft-break carets position at line start with alignment awareness.
• Page break suppression — Removed blank pages when pageBreakBefore appears directly after an explicit page break.
• Textbox table rendering — Tables inside textboxes render with correct alignment and text flow.
• Block identity repair — Duplicate block identities fix automatically on compile.
• Font substitution evidence — Font reports carry per-face evidence (metric-safe, visual-only, glyph exceptions).

Fixes

• Empty table cell selection — Dragging a selection into an empty cell no longer collapses.
• Multiline selection rendering — Interior lines of multi-line selections render full-width highlights.
• Empty cell geometry — Empty cell paragraphs resolve to a valid position for interaction.
• Image alpha on export — Images with transparency now preserve alpha on DOCX export.
• Linebreak text selection — Search spans and selections spanning text+linebreak+text now coalesce correctly.
• Font toolbar updates — Toolbar rebuilds when document fonts change or editor switches.
