Nvda: NVDA narrate table title(aria-label) twice

[kolaps33]

Steps to reproduce:

1.Navigate to the example page:
https://jsfiddle.net/kolaps33/1v34xwp6/15/
Example was done based on the aria example: https://www.w3.org/TR/wai-aria-practices/examples/table/table.html only labeling table was slightly changed.

1. set focus on button : "test button to set focus into page"
2. ensure NVDA is in browse mode
3. press "t" key to navigate into the table

Actual behavior:

NVDA narrate:
""""
students table with 5 rows and 4 columns
students
""""

Expected behavior:

NVDA should narrate:
"""" students table with 5 rows and 4 columns """"

I think, there should not be again repeating aria-label of the table.

Similar issue here. If the table label is updated, NVDA reads it 3 times in a row.

CC @michaelDCurran @feerrenrut There are several instances where NVDA does not suppress the AccDescription if it is the same as AccName. The VS Code issue linked above is an example of that. Firefox is smart in that it does not even expose AccDescription if it is identical to AccName, but other engines do not do that. I think NVDA should be smart to suppress unnecessary chatter if the two items match.

CC also @jcsteh for awareness.
