To preserve opened folder structure when dragging mail to folder

Is your feature request related to a problem? Please describe.

Folders are re-arranged during mail dragging.
It's probably an inappropriate design rather than an error.

Describe the solution you'd like

To preserve open folder structure as it was before dragging started. Allow to drop mail to the already opened folder.
Don't move with the folder structure at all (move it only if I need to drag above / bellow visible part).

Describe alternatives you've considered

Additional context

Currently, when I open some folders in the left side and then I drag any mail into it (to the left), all opned folders are closed, some other (maybe first ?) folder is opened. I have to navigate to my target folder (which was previously already opened) through the bumpy path to the target folder (which is totally non-intuitive and user anti-friendly) and then I can drop the mail to desired target folder.
Additionally, I need to go this rough path for every mail to the same target folder.

Start by reproducing the drag-and-drop behavior in the left folder tree with several folders expanded, then locate the frontend entry point responsible for folder scrolling and expansion during mail dragging. Done means expanded folders remain open and a mail can be dropped into an already visible target folder without forcing the folder structure to change.
