python 3.13.5 ttktreeview

[cmiles69]

Bug report

Bug description:

'''
In python3 version 3.13.5 and Tk version 8.6.16
If i were to add an ttk.treeview on the right frame the buttons in the left frame all turn blue from grey.
If I remove the treeview alltogeather, the buttons return to grey.
Also happens with ttkbootstrap.
No amount of background options on the buttons nor style options on the tree view changes anything.
