--------------------------+-----------------------------
 After upgrading to 4.9.1, caption widths expressed in percentages are
 converted to max-width in pixels. A caption setting of width="100%" is
 converted to max-width="100px" in the page source. Below is the effect in
 both my custom theme and in the Twenty Fifteen theme.
 Post text: [caption id="attachment_864" align="alignnone" width="100%"]
 Page Source: <figure id="attachment_864" style="max-width: 100px" class
 ="wp-caption alignnone">
