The entered character will be replaced with the unconfirmed character when the cursor is moved before confirming the character

This is reproducible with Japanese input.
It is not possible to reproduce with English input.

How to reproduce
1. Use Qt Example text finder (https://doc.qt.io/qt-5/qtuitools-textfinder-example.html)
2. Write some texts in the keyword field and confirm the texts.
3. Locate a cursor in the middle of the texts of (2) and type e.g. "@"
Don't confirm the character. Keep it in editing mode.
4. Move the cursor by tapping other parts of the texts.

Expected result :
The cursor is positioned without changing the texts

Actual result :
Characters are replaced by the unconfirmed character (i.e. @) See qtbug95031-actual-result.png
