move directionOfEnclosingBlock() to be global so that it could be reused

• Component: HTML Editing
• Status: RESOLVED FIXED

[Xiaomei Ji]

we should provide a directionOfEnclosingBlock(Node*) so that it could be reused in SelectionController and other functions in visible_units.cpp, such as moving caret by word in visual order (which needs to know the direction of box and enclosing block, and the caret movement direction).

This isn't right.  You're calling anchorNode() here even though the original code called containerNode().

This isn't really a standard way of writing a change long entry.  Please do:

move directionOfEnclosingBlock() to be global so that it could be reused
https://bugs.webkit.org/show_bug.cgi?id=57233

Provide global function directionOfEnclosingBlock(Node*) so that it could be
reused in SelectionController and other functionalities that need enclosing
block's direcionality, such as moving caret by word in visual order.
