This appears to be Firefox only (I'm using latest version, 43.0.4). Menu version 7x.3.0-rc5; Drupal 7.41. Mac EC, but this happened on previous versions.)

Click on any menu item, then click the second item (eg, Structure > Content Types). If I do not move the cursor off the menu, those dropdown items remain even after the new page appears. I have to swipe over the menu then click into the page to get it to go away.

UPDATE

Just to be sure, I installed 3.x-dev, and the problem is resolved. But I still want to report this on the rc5 version. Thanks.
