Steps to reproduce:

• create an app with solara.FileBrowser()
• the Filebrowser starts in the cwd (C:\Users...), in the app click '..' until you are at 'C'

The filebrowser now shows the as if it was in the cwd instead of disk root

Similar issue when using eg solara.FileBrowser(directory="D:\\")

FileBrowser starts at D:\ correctly
click to enter 'my_folder'

click '..' to go back

note the lacking trailing backslash
click 'my_folder' again

now backslash is missing

click '..' again:

This is on windows and solara 1.33.0
