v3.3.0

Design

• Redesigned the full editor icon set.
• Increased the corner rounding (border-radius) across the editor UI for a rounder look.

New Feature

• A lineBreakClearStyle option has been added — when true, pressing Enter at the end of a line starts a fresh line without carrying the caret's inline style nodes (bold, italic, color, links); the line-level element and its attributes are preserved. Affects the end-of-line case only.
• toolbar_sticky option now accepts a position: 'sticky' | 'fixed' field (default 'sticky'); 'fixed' forces the JS position: fixed sticky engine over native CSS position: sticky for environments where CSS sticky misbehaves.
• placeholder_line option now accepts an object for per-type hints, keyed by tag name (pre, blockquote, ...) or a category sentinel (@line, @normalLine, @list, @brLine, @closureBrLine, @block, @closureBlock), resolved most-specific to least. The string form is unchanged.
• A menu.subscribeDropdownOff(callback) method has been added to subscribe to dropdown-off events; it returns an unsubscribe function.

Enhancement

• Added Esc key support to close open toolbar dropdown menus, including dropdown-free menus like fontColor.
• Updated the table cell controller so the unmerge button is hidden instead of disabled when there are no merged cells, matching the merge/split button toggle.

Bugfix

• Fixed an issue where the off-screen focus-temp input (.__se__focus__temp__) was a keyboard tab stop; it is now tabindex="-1" and no longer reachable by Tab. #1677
• Fixed a bug where the finder toolbar button did not toggle the finder panel closed when pressed again.
• Fixed an issue where pressing Enter on an empty line inside a block (e.g. <blockquote>) with content below placed the new line and caret below the lower chunk instead of between the two chunks.
• Fixed an issue where opening a dropdown-free plugin's sub-panel from the command menu (e.g. fontColor's color-picker hue slider) closed the entire menu; the flyout now closes only when the plugin commits.
