These loops may run script. In `HyperTextAccessible`, it calls `RemoveRangeAndUnselectFramesAndNotifyListeners`. So, chrome script which is not directly related to this module may run in each call. I think that using `RemoveAllRanges` is better for here. Before bug 1735446, this loop tried to keep first range, but accidentally, I changed this loop delete all ranges. However, `SetSelectionBoundsAt` will add a range if it's required and there is no bug reports. Therefore, I think keep the new behavior is better. In `nsRange::DeleteFromDocument`, the loop may run mutation events too. Therefore, it needs to store all ranges first. Then, the preceding patch changes the behavior here if a selection range is moved to different root. Previously, it was deleted, but now, they are not touched.
