Steps to reproduce:

  1. Enable layout.css.overflow-clip-box.enabled.
  2. Load the attached testcase.

Expected result:
There is no red area.

Actually result:
The clip area established by overflow-clip-box:content-box shrinks because of the scrollbar.

overflow-clip-box: content-box is only used internally in the inline axis for <input>, and <textarea> in forms.css. <textarea> can have scrollbar, so this bug may or may not affect it.
