Auto completion box closes while typing.

(Tested only on Windows 11 so far.)

The auto-completion dropdown in the text editor (C++ editing) closes automatically when the second character is typed. Example: (|-symbol is the cursor in the editor)

QVariant v;
v.t|

will open the dropdown for auto-completion. When I then type an 'o', like

QVariant v;
v.to|

the dropdown automatically closes and I have to manually reopen it via <ctrl>+<space>.

See the attached screen recording for clarification. As can be seen there, with the second letter after the dot, the dropdown closes. (I press <ctrl>+<space> to open it up and proceed.)
