Issues with Expand Columns or Rows or All and with Collapse Columns or Rows

Hello all,

I have come in need to configure a pivot grid able to expand/collapse only rows or columns or all together, and I have found quite some issues.
As long as I have to only expand (wathever it might be from only rows, columns or all), I can use your expandAllData function, which works almost for every test case. And here comes my first issue:

If I have configured a pivot grid with a hierarchy field (which contains at least two levels of hierarchy) and a second node field following the hierarchy one, once I click the expand all button, which fires your
expandAllData function, the pivot drills down all the hierarchies but does not open the last node field. This happens the same even trying to call expandAllData(true, "columns"), for reference.
This behaviour is the same both for api and json datasource type.

My second issue is the following one, which happens only for the api datasource type grid:
I have configured a pivot grid, with the same configuration as above. If I manually open the hierarchy levels in the columns and afterward proceed to close them,
wether by the collapse all button (which fires your collapseAllData function) wether it is manually, the grid seems to remember the last hierarchy level manually opened and when I try to open again the hierarchy levels right
from the start the grid opens all of them hierarchies until the last one opened by me.
This behaviour is kind of misleading to me. I expect that if I drill up all the levels, when I try to open them again I have to go through every level all over from the start.
As said, this happens only for the api datasource type, for the json datasource type it works fine.

As per my third issue:
I have configured a pivot grid, with the same configuration as above. If I click on the expand columns button, which for reference fires your expandAllData(true, "columns") function, the grid acts in a strange way..
meaning that it does open all the levels in the columns (except for the first issue related nodes) and at the same time it tries to open some rows levels too, apparently in a complete random way.
This behaviour happens clearly in the json type datasource. As per the api type datasource, it tries to open the row levels too and you can see that as some icons go from closed to opened position.
Note that this does not happen if you exchange the columns data to the rows and viceversa, this only happens with the configuration provided, so hierarchy levels in columns and nodes in rows.

And for my fourth and last issue:
I had to implement my own solution for collapse rows/columns, ever since there is not an opposite function to expandAllData which can close only rows or only columns. I could not even use runQuery or refresh,
since they do not update the expands and drills object contained in the slice.

I will provide an example where you can see my workaround, which just manipulate these objects in the slice and then proceed to
reassign the report itself, which I don't like to be honest.

Is there a possibility for you to implement somenthing as collapseAllData(withChildren?: boolean, axis: string)? I know your collapseAllData function exists but it does not help me in this case.

I will attach a solution where you can reproduce these issues, with both api and json datasource type.

I hope everything is clear and readable.
Thank you and hoping to hear from you soon.
