It is possible during a layout a block to shift vertically. This means that the lines to fall in a region with a different width need to be recomputed. The detection of the first line is erroneous if it falls in between regions.

This doesn't seem to reproduce anymore (Canary, Mac nightly). Closing, unless some other way to reproduce it can be found.
