Placeholder with a width of 0dp has consequences on the height of the content view

[fabiogrum]

Tested CL versions: 2.0.4 and 2.1.3

When setting a width of 0dp on a Placeholder the content view (in this case a Button) has a much bigger height, or it's not visible, like if it's not taking into account the wrap_content height of the placeholder.

In this screenshot, you can see that the button it's too big in height and also the button text is not in the right position:
