Automatic update from web-platform-tests
[Editing] Double-click selects wrong range for any element styled
as float.

The CL addresses the bug where double click on any list item
selects multiple list items when list item has floating style.
When there are multiple list items and anyone is selected using
double click, it selects all the list items along with the one
on which double click was performed. This happens because in
|ComputeInlineContentsAsBlockFlow|, float style is not considered
as text segment boundary and the selection is expanded for all.

Also, for other cases involving floating style on element, the
selection is not as expected as selecting a float element by
double click selects everything. This is fixed by removing the
condition which expands the selection when the element has a
floating style.

Firefox has the behavior similar to what we get after the fix
i.e it doesn't expand the selection for floating elements. Webkit
however, seems to have the same bug as chromium expanding the
selection for floating elements.
