IME, TextBox - TextBox does not scroll at the end of line when entering CJK characters via IME

[lnxon]

Describe the bug
You enter CJK chars into TextBox using IME and when the caret reaches left end of the available space, the TextBox should scroll horizontally to show the caret position. But scrolling happens only when you press "enter" and convert the preedit text.

To Reproduce
Steps to reproduce the behavior:
(REFER TO VIDEOS BELOW)

1. Run ControlCatalog.Desktop
2. Open "Clipboard" pane
3. Enter long CJK line into the textbox
4. When caret reaches the end of available space, you see error (textbox does not scroll until you hit enter key).

Expected behavior
TextBox should scroll each time any key is pressed and a char is added to the preedit text.
