Tooltip text not read in Office ribbon sub-menu items

[Qchristensen]

When navigating sub-menu items in Office (2016 at least), tool tip information is only available by moving the mouse to the current navigator object (or physically). The only way to have NVDA read the information is then to physically move the mouse over the tooltip.

To reproduce:
Open Excel (Word has several examples of this, but Excel has more)
Press alt+m to open the formula ribbon
Open any of the sub-menus, I pressed E to open "time and date"
Down arrow through the items. NVDA reads the function names but no tooltip appears.
Press NVDA+numpad Divide (laptop: NVDA+SHIFT+M) to move the mouse to the current item (I was on "DAYS".
Physically move the mouse slightly down and to the right to have NVDA read the tooltip.
Press NVDA+numpad Multiply to navigate to the object under the mouse.

I then captured the following with NVDA+F1:

"nput: kb(desktop):NVDA+numpadMultiply
IO - speech.speak (14:24:13):
Speaking [LangChangeCommand ('en'), u'Move navigator object to mouse']

@Qchristensen the tooltipps seem to be reported properly now. Could you please test with NVDA 2019.1 please?
I have tested just now in Office 2016 and 365 and I can not reproduce this issue.

[Adriani90]

In Office 2010 NVDA 2019.1 reports them also properly.

[Qchristensen]

In my example, the date and time formulas, the first one is DATE. NVDA Reads:
DATE (Year, month, day)

If you hover the mouse over it however, it displays that text in bold in a tooltip. In the same tooltip, it also says:
Returns the number that represents the date in Microsoft Excel date-time code.

Ok when testing this in Excel 365 I don't get the information mentioned by Quentin. So it seems this issue is still reproducible.

I wonder whether #8124 is somehow related to this issue.
