Unabe to 'save as' a notebook inside folder name which contains space character

[HarshithMjh]

Steps to reproduce:

1. Create a folder which contains space (Eg: 'Untitled Folder')
2. Navigate inside the folder and create a notebook
3. Go to file -> Save As
4. It would already contain the folder name. But space would be replaced with %20. Enter the name for the new notebook to be created after '/'.
5. Click on "Save". It fails with the error.

Manual resolution:
Remove the %20 manually. Then click on "save". It works

Hi @HarshithMjh - I can confirm this is an issue in the Notebook frontend. It does not occur using Lab, so there's some missing escape logic in the save-as functionality.

We're minimally "staffed" on frontend maintainers at the moment, so until a fix can be contributed, using Lab or the manual replacement workaround will need to suffice. Sorry for the inconvenience.

Wow - how soon we forget (and it gets worse every year)! Thanks @stephenisau - this will be fixed in the next release.
