[sidebar] Dimmer missing when using multiple sidebars

[AdrienLZ]

Bug Report

I'm using a top menu with multiple items, each of them opening a sidebar with an overlay transition.

When I click one item from the menu, the sidebar open and the dimmer appear, if I use the same item again, the sidebar collapse and the dimmer disappear, all is fine.

BUT if I click an item from the menu, the sidebar open and the dimmer appear THEN if I use an other item from the menu, the first sidebar collapse, the dimmer disappear and in the same time the second sidebar appear, but NOT the dimmer.

(Have to say: It work well using transition:"push")

Steps to reproduce

(On the jsfiddle)

1. Open a sidebar .
2. Open an OTHER sidebar.

Expected result

I expect that the dimmer appear with the sidebar.

Actual result

The sidebar is open but without the dimmer.
