Bug when entering or leaving opacity mask

Question

I don't know when this started happening but it's recent. Most of the time, I can't enter Opacity Mask. When I manage to enter (after doing the same steps tens of times), then I can't exit it.
Steps:
- Select an object with an opacity mask
- Click "Opacity"
- Click the opacity thumbnail
At this point I should enter Opacity Mask mode, but it's not happening. If I repeat the same steps 5-10 times it will eventually enter it. At that point, if I try to exist this mode through the same steps (Opacity panel -> Left thumbnail), it will not exist Opacity Mask mode.
If I uncheck/recheck the Clip checkbox before clicking the thumbnail, it seems to work.
 
I've already restarted Illustrator and reinstalled it. It's something with a recent version I think.[Edited by Moderator]

@vpck I remember to have seen this reported. It only happens in the Appearance panel, but still works in the Window > Transparency panel.
