Escape key during IME composition

Escape typically cancels IME composition or closes the candidate window. In Edge, Firefox, and other engines, timing and whether partial text remains in the DOM differ—Arabic and Korean IME cases show cross-browser variance.

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.

Paste during IME composition cancels or corrupts composition

Pasting from the clipboard while IME composition is active may cancel the composition session, replace the wrong range, or interleave pasted text with unfinished syllables—Firefox and Chrome show different behavior for Korean and Hindi IME paths.
