Created an attachment (id=32103)
 --> (https://bugs.webkit.org/attachment.cgi?id=32103&action=view)
updated patch

Currently, the methods in question are called on RootInlineBox objects only,
AFAICT, so there should not be any observable effects (the mentioned behavior
can only happen if called on InlineFlowBox objects, basically).

Only the removal of the square runtime behavior when the remaining nodes in a
tree are all empty InlineFlowBox objects could be effective, but the conditions
for that are more theoretical in nature (i.e., would probably require to have a
pathological case to have any measurable impact).

Updated the ChangeLog accordingly.
