How to reproduce? When the tabs to less, no button is under the mouse, in Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:59.0) Gecko/20100101 Firefox/59.0 ID:20171130220131.

¡Hola Yang!

Here's a short video https://www.screencast.com/t/xDJix4qVh1

Internet Explorer does better when on a closing tab spree, see https://www.screencast.com/t/Q45VM77J

Okay, I see the same thing, but the button never appears to me mouse below.

Not like a regression, it appears in Firefox 53, 55, etc.
