I've just come across the same problem.
For future reference, adding the following code before using a Treeview widget
will fix the problem:
def fixed_map(option):
# Fix for setting text colour for Tkinter 8.6.9
# From: https://core.tcl.tk/tk/info/509cafafae
#
# Returns the style map for 'option' with any styles starting with
# ('!disabled', '!selected', ...) filtered out.
# style.map() returns an empty list for missing options, so this
# should be future-safe.
return [elm for elm in style.map('Treeview', query_opt=option) if
elm[:2] != ('!disabled', '!selected')]
style = ttk.Style()
style.map('Treeview', foreground=fixed_map('foreground'),
background=fixed_map('background'))
