When creating a new document or creating a PDF a file dialogue appears, which is hard to position. You cannot scroll to the top of the tree. It stops at position 2 or jumps back to the initial directory, its a bad component. Also for PDF the initial directory should be the last one chosen, but it's the one from the save dialogue.
Steps to Reproduce:
1. open document
2. press button for PDF
3. the file dialogue appears
it's positioned somewhere by old memory
it should be positioned to the last directory used in that context
