Can't distinguish between regular (!) and full-width exclamation marks (！) in folder names?

For example, if you have both !a and ！a folders in the same path, you can't enter the ！aaa one
when I tried cutting and pasting the ！a folder to another location and then back again, it doesn’t show up in the left sidebar list at all. Check the pic

Tried to replicate it with a fresh; 27.00.0500, no problems, neither entering nor disappearing from the tree...

！a = \uFF01 + a
