8341453: java/awt/a11y/AccessibleJTableTest.java fails in some cases where the test tables are not visible

[GoeLin]

I backport this for parity with 21.0.7-oracle

The issue addressed by this change is fixed.
But the test does not exactly do what is requested by the description.
Maybe the description is shaky, or mac behaves different from windows and
the description is not tailerd for this. E.g., it does not anouce the cell position if
entering the table. It does so when reordering the columns. Also, some of the
buttons in the third test are not visible. They work, though.
I verified this is the same if run on jdk head.
