When I add, delete and change elements or can simply add/delete/change element metadata, the tree can (very often) collapse. Previously (maybe a year ago), it was always stable. Now it has become extremely inconvenient to work with it.
Of course, there is a button that expands the entire model, but this is also inconvenient, since I have a rather deep and rich model and I have to open (search) for elements in a multi-level model for a very long time. In addition, this does not save from the fact that the model tree can close under certain circumstances.
I am sure that this behavior is incorrect, because for several years the semantic model tree behaved adequately (for example, like Windows Explorer) and in rare cases collapsed itself. Now it is impossible to use! What to do with this?
