Chinese IME conversion delay and partial conversion in Safari

IME candidate list timing and conversion (kanji, hanzi)
Japanese kanji conversion and Chinese character selection depend on the IME candidate window. Delays, wrong ordering, or Safari-specific lag can cause users to commit the wrong character or see candidates that do not match the underlying buffer—especially under load or in complex layouts.

Details
Japanese kanji conversion and Chinese character selection depend on the IME candidate window. Delays, wrong ordering, or Safari-specific lag can cause users to commit the wrong character or see candidates that do not match the underlying buffer—especially under load or in complex layouts.
Problem Overview
Conversion is not just a browser issue—IME software matters—but the host app (your editor) can worsen latency with synchronous layout, heavy input handlers, or forced layout reads.
Observed Behavior
- Safari: conversion delay vs Chrome for the same input method.
- Rapid typing: candidate list lags behind buffer updates.
Impact
Wrong characters committed; power users notice “sticky” conversion.

Number keys for IME candidate selection (Japanese and Chinese)
Many IMEs let users pick candidates with number keys 1–9. In contenteditable, those keys may be consumed by the IME, intercepted by the page for shortcuts, or mis-handled by Safari—causing wrong selection or cancelled composition.

Blur and focus during IME composition (CJK and Japanese Safari)
Moving focus away from the editor while composing text (Chinese, Japanese, Korean) can cancel composition, commit partial text, or leave the IME candidate window out of sync. Safari often shows distinct behavior for Japanese; Chrome behavior for Chinese/Korean is covered in related cases.

IME composition when focus moves between elements (Korean and others)
If the user switches focus to another field, button, or nested contenteditable while Korean (or other) IME composition is active, browsers differ on whether composition is committed, cancelled, or leaves orphan state. Chrome, Safari, and Firefox do not agree; mobile adds more variance.

Scrolling cancels or disrupts IME composition
User scrolling the page or scrollable editor while the IME candidate window is open may cancel composition or move the caret out of sync—reported on iOS Safari with Japanese IME and Android Chrome with Chinese IME when scroll containers move the editing context.

Tab key during IME composition (focus vs indent vs IME)
Tab moves focus by default. During IME composition, Tab may cancel composition, cycle candidates, or be captured by the editor for indentation—behavior differs for Chinese, Thai, and Safari vs Firefox.
