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
https://cgit.freedesktop.org/libreoffice/core/commit/?id=424312aa99307da9f0ee60ea6e3213b2b3dc26b4

Then in 7.0.2, Noel fixed the crashing with
https://cgit.freedesktop.org/libreoffice/core/commit/?id=445cf499666f21c2d480ce1df9ce6004b9450b64

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+.
