Wrong positioning when embedding in a flex container

[timeu]

When putting a paper-dialog and a paper-dialog-scrollable' inside a body that has the classesfullbleed,verticalandlayout`, the offset will be wrong.

Reproducable: https://jsbin.com/dizison/edit?html,output If you remove the layout and vertical classes from the body tag it will work fine.

The problem is that this line will result in a negative offset: https://github.com/PolymerElements/iron-fit-behavior/blob/master/iron-fit-behavior.html#L229

I'm sorry, but the reported issue is a little too vague to be actionable. Can you provide screenshots of the expected result and the actual result from your test case, and then re-open? Thanks!

It seems that the issue isn't reproducable anymore.

Soem more infos: When I created the issue, the problem was, that the dialog was bigger than the visible screen because var sizingOffset = this[offsetExtent] - this.sizingTarget[offsetExtent]; returned a negative value (when the body was flexed) and thus maxHeight was bigger than it should be.
