Media library crash With several subfolders

i have a folder with more than 5000 subfolders. if i click on this folder, the website will stop. next time if i open media files, the selected folder will be that folder and the site crash again.

i think the tree sidebar is not a good solution to show the folders. it's better to show folder inside the content panel and doing pagination to show few folders every time or doing lazy loading to load the folders in the tree panel.
