Move to beginning or end of paragraph ignore contenteditable="false"
Ctrl+A/Ctrl+E are mac-specific key binding:
Ctrl+A: Move to the beginning of the line or paragraph.
Ctrl+E: Move to the end of a line or paragraph.
Consider this test case:
Ctrl+A was pressed, the caret moved to the end of "link".
But the expected position of the caret is the beginning of the line.
Before this patch, MoveToBeginning/EndOfParagraph couldn't cross the
editing boundary. This patch changes MoveToBeginning/EndOfParagraph
to be able to cross the editing boundary.
