Using the Windows 10 Chinese Pinyin keyboard can cause the editor to crash

When the Windows 10 Chinese Pinyin keyboard is being used to enter text into a context menu in a graph editor and is interrupted by the context menu being closed, the editor freezes and results in a windows error message. No callstack is generated but the Windows Event Viewer logs are attached.

This has been tested with the Pinyin keyboards provided on Windows 7 and the crash did not occur, this is specific to Windows 10.

1. On Windows 10, navigate to Control Panel > Language > Chinese (Simplified) > Chinese (Simplified, China) and then wait for the language files to download
2. Open any project in the editor and open a blueprint
3. While focused on the editor, click the "ENG" beside the clock in the Windows Taskbar
4. Select the newly added Chinese Pinyin keyboard
5. Right-click in the blueprint's event graph
6. Type some random characters but do not hit enter. A display with Chinese characters should appear.
7. While this display is up, click on an empty spot in the event graph (anything that would make the context menu disappear)
   Result: The editor stops responding, resulting in a windows error message
   Expected: The context menu should close without any issues
