Doing a configuration of the tkinter combobox for the dropdown list with:

    style = ttk.Style()
    style.configure('TCombobox', postoffset=(0,0,width,0))

results in no changing of the combobox.

In Python 2.7.16 or generally in python 2 this functionality works well.

Please see the sample source-code attached.

This is a strange bug, as the fix is simply to explicitly give the style (`style='TCombobox'`). This is, however, a Tcl/Tk issue as it can be reproduced in wish (I used the script attached). I therefore ask you close this issue as third party (you can take it up with the Tcl team if you want).
