MouseWatcherBase hide_regions() access violation?

[ponyboy837]

This access violation (https://gyazo.com/8b26f953fcd1d576d44f35e24ac0a8ae) happens when trying to hide any visible regions by the MouseWatcher. (Which is only called to set _show_regions to false anyways, Which is done to skip a weirdly failing assert { nassertv(_vizzes.size() == _regions.size()); } which is done in the add_region function.

If you need to test this for yourself. The project this issue is found in is public and is located at https://github.com/theclashingfritz/libotp.

This does not appear to be a bug in Panda, but a bug in the referenced libotp code. MouseWatcherRegion is a reference counted object, so it should be stored in a PT() in the ClickablePopup class. It should also not be explicitly deleted, since panda will do that for you.
