Dragging And Dropping In HTML Tables Breaks NVDA Table Navigation

STR:
I can't find a website to try this, but this has happened many times. When you are in a table that requires you to drag, say, a file from one column to the next (imagine you could drag a file from the private column to the shared column to share it), start dragging the element with the left mouse button lock key, move to the other column using alt+ctrl+right, route the mouse cursor to your current position, and release the left mouse button.
Expected result: navigating back to the previous cell and outside that cell should be working fine, and you should get the row and column count just like in any other cell.
Actual result: navigating back to the previous cell (using either up arrow or alt+ctrl+left) would get you back to the cell, but rather than hearing, say, "row five column 1", you just hear "cell". Using alt+ctrl+left/right/up/down to navigate in the table will not work in this cell anymore. The only way to get it to work again is to press insert+f5.

I'm afraid we really need a proper str for this to reproduce. Also, it is necessary to know what browser this happens in. I'm tempting to close this as invalid due to the lack of steps to reproduce, but I'll leave this open, at least for this round of triage work.

@LeonarddeR, @parham, here is an exapmle website. This is a sample of an java script plugin which brings drag'n drop functions to the tables:
http://www.danvk.org/wp/dragtable/index.html

there are also jQuery tools for this.

However, with NVDA 2018.3.2 I cannot reproduce this issue in Firefox and Google Crome. In IE11 this function is not available and in Edge mouse routing is not working. I think this is solved for FF and Crome by #8833 and #8479.

Ofcourse it can depend on the tool which has been used by the developer to create such tables. This one works well. But I guess this issue was related to mouse routing so it does not depend which tool has been used.

@LeonarddeR I suggest to close this issue.

@LeonarddeR your thoughts on my last coment above are very appreciated. Thanks.

@mltony could you please test the website from my comment above according to this issue? I cannot reproduce it in traditional browse mode. Can you see this issue at all?

@Adriani90,
In Chrome column dragging works fine in both fast and traditional browse mode
In Firefox it does not work in either modes, but the symptoms are different from what is described above. In my case dragging just doesn't happen at all.
Given this, I don't think that there is any evidence fast browse mode would break drag and drop functionality.

I'm closing this as works for me as per above comments.
