* NS_BLOCK_HAS_FIRST_LETTER_STYLE means that the block has first-letter style,

*
* NS_BLOCK_HAS_FIRST_LETTER_CHILD means that there is an inflow first-letter
* frame among the block's descendants. If there is a floating first-letter

* bit is not set. This bit is set on the first continuation only.
