            Bug ID: 274702
           Summary: compositionend Event Not Triggered When Clearing
                    contentEditable Element
           Product: WebKit
           Version: Safari 17
          Hardware: All
                OS: All

Test Environment:
•macOS: Version 14.4.1
•Safari: Version 17.4.1 (19618.1.15.11.14)
•iPhone: iOS 17.4.1
•Safari: Version 17.4.1 Mobile/15E148 Safari/604.1

Description:
- In contentEditable elements, when input is cleared using methods like elem.innerHTML = '', the compositionend event does not fire as expected. This issue affects text input handling and disrupts the expected behavior of composition events.

Steps to Reproduce:
1. Create a contentEditable element in a webpage.
2. Start typing text in the contentEditable element to initiate a composition (e.g., using an IME for Japanese). (Currently, Korean does trigger composition event https://bugs.webkit.org/show_bug.cgi?id=274700)
3. While the composition is ongoing, clear the content using JavaScript: elem.innerHTML = ''.
4. Observe that the compositionend event does not fire.

Expected Result:
- The compositionend event should be triggered when the content of a contentEditable element is cleared, ensuring proper handling of composition termination.
