Region folding not working at last region, if region only contains indented code

I have a Python class with a lot of diffrent methods, wich I want to group into regions. For the first 5 regions the folding works perfectly normal, but after the the region PROPERTIES it just stops working.

Here is a stripped down version of my code.

# Bunch of imports


class Sprite:
    def __init__(self):
        ...

    # region MOTION

    def change_pos(self):
        ...

    # Some other functions

    def bounce_on_edge(self):
        ...

    # endregion

    # region LOOKS

    def set_image(self):
        ...

    # Some other functions

    def show(self):
        ...

    # endregion

    # region EVENTS

    def on_key(self):
        ...

    # Some other functions

    def clone(self):
        ...

    # endregion

    # region CONTROLS

    def wait(self):
        ...

    # Some other functions

    def repeat_until(self):
        ...

    # endregion

    # region PROPERTIES

    @property
    def image(self):
        ...

    # Some other functions

    @property
    def name(self):
        ...

    # endregion

    # region PRIVATE

    def _update(self):
        ...

    # Some other methods

    def _scale_and_rotate(self):
        ...
    # endregion

After further testing I noticed, that the problem does not occur espacially at the fith region, but on the last one. And the nature of the problem seems to lie in the fact that the region only contains indented Code. I don't know if this behaviour is intentional, or if there's an easy fix for it, but it's kind of annoying not being able to collapse the last region.

I hope I described the problem clearly and that my english is not too bad :)

Simplified form:

class Sprite:
    # region PRIVATE

    def _update(self):
        ...

    # endregion
