### Purpose
This closes#9400 by always expanding tildes when parent/subdir checks
are done.
### Testing
I tested this by creating folders with paths to parent or subdirectories
of the default folder that include a tilde in their path as shown in the
attached screenshots.
With this change, overlap will be detected regardless of wether or not
tildes are used in other folder paths.
### Screenshots
Default Folder:
Newly created folder (parent directory in this case)
