9 * Prior to Gutenberg 8.6, line-height was always enabled, which meant that wpcom
10 * users had been utilizing the feature. With the 8.6 release, though, line-height
11 * was turned off by default unless the theme supported it. As a result, users
12 * suddenly were no longer able to access the settings they previously had access
13 * to. This turns the setting on for all wpcom users regardless of theme.
