`InputEvent.getTargetRange()` should have actual delete range. It means that the range should contain the invisible leading/trailing white-spaces which need to be removed for keep them invisible, but should not contain the range of normalizing white-space sequence because they are not target of edit action indicated by `InputEvent.inputType`. So, we can use new path which uses the new white-space normalizer for computing the value of `InputEvent.getTargetRanges()` because difference of white-space normalizer shouldn't affect the deleting ranges (although, some existing path calls `DeleteNodeIfInvisibleAndEditableTextNode()` later so that the new method, `ComputeRangeInTextNodesContainingInvisibleWhiteSpaces()`, does not exactly same thing, but the result shouldn't become different in usual cases). This new path can test with some WPTs under `editing/other`. This patch creates new backspace/delete key handler when caret is at next to a white-space as `HTMLEditor::HandleDeleteTextAroundCollapsedSelection()` and creates helper methods of `WSRunScanner` to treat invisible leading and trailing white-spaces. Note that new failures are caused by the difference whether adjacent white-space sequence at deletion is normalized or not in edge cases. They will be fixed by the part.5.
