tableJumping_minimal.doc: clicking in table makes it jump every time.

Starting with LO 6.3.3 (and still true in 7.3+), every click inside of the table in this minimized document causes the table to jump back and forth. The cursor is lost in the transition as well, so it isn't simply a matter of scrolling and getting back to work. On the next click, it jumps again - making it basically impossible to edit the table contents. [In 7.3 master, after roughly 10 clicks, it settles down.]

This started in LO 6.3.3  with author Miklos Vajna on 2019-09-17 18:57:09 +0200

tdf#105330 sw: fix lost cursor on undoing nested table insert


It might be worth noting that sometimes you can see the cursor sitting somewhere in the middle of the first, mostly-empty page - somewhere that it should be impossible for it to be.

Further background related to bibisecting this:
Starting in 7.0, LO would crash after 4 or 5 clicks, because of Armin's

Then in 7.0.2, Noel fixed the crashing with

N.B. Somewhere in 7.0 (after the crashing started), it seems as if something has caused the jumping to settle down after a while. After about 10 clicks or so, it stops jumping around and editing can happen. This is seen immediately with Noel's 7.0.2 patch. That still holds true in 7.3+.

Oh, that's annoying. Reading the commit message of 	d5b50e74ee822e1c8402e3044e14799e47907ff8 now I recall that this was a revert: so the above problem was "fixed" between e4509eea8fc7c07ddff48edf0d4c015c2663d896 and d5b50e74ee822e1c8402e3044e14799e47907ff8, but only by causing side effects like bug 105330, i.e. I fear this never really worked.

Yes, that was my conclusion too, that your commit just exposed an existing problem.
