Display inherited properties
If enabled, the subtitle editor will consider some inherited properties when displaying the text.
The editing box displays the text based on subtitle's own properties.
For example, the text will be displayed in italics if the subtitle has an italics tag. But not if the tag is in the parent track or above.
If this option is enabled, the text is displayed using some higher properties.
For the moment this option only works the right-to-left formatting.
