In an implementation that offered genuine whole word selection, and
thus tackled with the challenges of Chinese, Japanese, Korean and
Vietnamese (both scripts, not just CJKV) as well as Thai, I would
expect the selections to be bounded by word boundaries.  Thus, if the
cited line break (labelled by '6') were not in the text, I would expect
double-clicking on the quadrat G37:Aa13:Aa13 to select all three words.

Looking at the rendering in
https://mjn.host.cs.st-andrews.ac.uk/egyptian/texts/corpus/pdf/Merneptah.pdf,
it is worth noting that the cartouche in Line 4 of the inscription is
not broken between lines.  I don't know whether this is to avoid
breaking the cartouche or to avoid separating the facing figure therein.
