But we removed the snapping from localSelectionRect. That seems like a bug fix, not a “no change” refactoring fix.

No need to put this into local variable any more if we are only using this once.

Marked this bug resolved fix following the landing of <https://trac.webkit.org/changeset/223699> (bug #178232) that shared more code between InlineTextBox::paintSelection() and InlineTextBox::localSelectionRect(). The pointer to reference conversions that were made in the proposed patch for this bug (attachment #236101 [details]) were made in <https://trac.webkit.org/changeset/174876> (bug #137858).

For completeness, we cannot remove the logic to compute the enclosing integral rectangle from localSelectionRect() as the patch on this bug (attachment #236101 [details]) attempted to do because localSelectionRect() is used to answer calls to the Web API Element.getClientRects() and other objects that override localSelectionRect() return the enclosing integral rectangle of the selection. For consistency we would need to update all overrides of localSelectionRect(), including the override in InlineTextBox. Bug #138913 is tracking this effort.
