Regression: Popups using JToolTip components do not respect their location

[Chrriis]

While testing the new features (sorry @DevCharly, I did not have much time to do it earlier!) I stumbled upon this major regression for us: the location of a popup is not respected:

It seems that the use of JToolTip is a problem. If I replace with a JPanel, then the position is correct (but not the look).

Here is the test case:
TableTestWithTip.zip

(another problem shown in this test case: "table.setShowGrid(true)" is not respected by the boolean column. Should I open a bug?)

Sorry, commit 8925c27 (fix for #164) is responsible for the wrong tooltip location.
Working on a solution...

Regarding missing grid lines in boolean column: this is normal because table intercell spacing is set to 0,0 in FlatLaf to avoid gaps in selection:

You should also set intercell spacing if showing grid:

table.setIntercellSpacing( new Dimension( 1, 1 ) );
