data source manager not opening with correct sub menu for point cloud datasources

[DR-azery]

Describe the bug

if you select Layer -> Add Layer -> Add Point Cloud Layer the data source manager opens, but not necessarily with the Point Cloud menu selected. It will open with the menu used the last time the data source manager was used. For all other layer types, the data source manager directly opens with the correct menu.

How to Reproduce

• Open Qgis
• Open new project
• select Layer -> Add Layer -> Add vector layer
• select 'close'
• select Layer -> Add Layer -> Add point cloud layer
  Menu opens, but still for vector data.

Additional context

* select Layer -> Add Layer -> Add point cloud layer
  Menu opens, but still for vector data.

@DR-azery works as expected here on QGIS master on Linux.

Thank you for your analysis. I have made a little video showing the issue. You can find it in the zip file in attachment. I'm sorry for the lower resolution and the format, but I did not have many tools available for the recording.

You will see that I do 5 tests:

1. add layer -> add raster layer : the menu opens with the correct layer type selected on the left : OK
2. add layer -> add SAP HANA spatial layer : the menu opens with the correct layer type selected on the left : OK
3. add layer -> add point cloud layer : the menu opens but at the left, the selection is still on sap hana and not on point cloud: NOK?
4. add layer -> add vector layer : the menu opens with the correct layer type selected on the left : OK
5. add layer -> Add DB2 spatial layer : the menu opens but at the left, the selection is still on vector layer: NOK?

So, for certain menu items, the data source manager opens with the requested type selected, and for others not. Obviously not a very big issue, but sometimes a little annoying.
If I can do something more to provide more information, just let me know.
