Description:	When running the attached script `xpnativeBug.tcl` on Windows, the ttk::menubutton indicator of the `xpnative` theme exhibits the artifact shown in the screenshots contained in the left half of the pictures `menubtn_100.png` and `menubtn_150.png`. The right screenshots show the expected appearance, obtained after fixing the bug that causes the issue. The screenshots were taken on a display with 100% and 150% scaling, respectively, and magnified by a factor of 2. The wrong appearance of the ttk::menubutton indicator is due to the use of the element spec `GenericElementSpec` for the `Menubutton.dropdown` element. The fix consists in using the spec `GenericSizedElementSpec` and the flags `(SM_CXVSCROLL << 8) \| SM_CYVSCROLL`.
