Tooltip doesn't work on {{paper-switch}}

[Maxim Kirilchuk]

Hi. I've updated ember-tooltip to v3.2.0
I've noticed that tooltip doesn't appear in case of using paper-switch. It attaches trigger to sibling but not to parent element. It works only if I set target as paper-select. In 2.x it works well.
And also you forgot to mention in the migration doc that target changed to targetId

Sorry it's taken me so long to take a look at this.

It seems that it occurs when there is no other content inside the paper-switch. This results in the .md-label element not having a width or height, which prevents it from being toggled on mouseover, as there is no target to interact with. (The target will, by default, be the .md-label element within the paper-switch component)

The solutions that I can think of are:

• Provide some label contents
• Customize the CSS of the .md-label for the specific paper-switch invocation to exist as a workable hover target. Could maybe give it a relative position and move it over the switch?
• Could maybe try specifying targetId where the value is the ID of the paper-switch element and set side to left-start (by default tooltips are centered, and paper-switch seems to take full width by default, so your mileage may vary here)

Ideally, it seems you'd want to attach it to the .md-container inside paper-switch instead, but there doesn't seem to be a way with ember-paper to attach an ID to that, as far as I can tell.

Closing this, as I believe it's not something that's fixable within ember-tooltips, and requires special handling in either the application or ember-paper
