I so hoped you had a better idea :) Too bad then.
At least the code is isolated and does not interfer with other code, so if we hopefully one day can discard it again due to native selection possible it could be simply dropped again without any problems.

Added a longer APIDOX comment to KoTextLayoutArea::generateCharAreaInfos() where also all other area methods have all their comments.

But isn't that ensured by the separate loops for the header rows and the `firstRow` calculation?
I just had another look, and now even less than before grasp what both `testRow` and `visitedCells` are supposed to do in the end.
Need to catch you on irc to teach me :)
So keeping this TODO for now and doing with commit including it, as something here either is fishy or needs better documentation for newbies like me :)

So they now carry logic for a currently single use-case, which also is not the most typical. Surely not a lot of code, but ideally this special need for the Okular plugin should not add its payload for everyone.
