Screenshot showing difference.

SUMMARY
Browser shows 3,002 files, properties of the same folder shows 3,000. 

STEPS TO REPRODUCE
1. Create folder
2. Copy a large number of files (>=200) into folder.

Seems to be that if there are >=200 files the issue appears. At 199 the count is 199, at 200 the count is 202.

OBSERVED RESULT
Counts do not match.

EXPECTED RESULT
Counts should match.

ADDITIONAL INFORMATION
* For n >= 200, count in browser "size" column is n+2, count in properties of folder is n
* In folder: `ls -1 | wc -l` -> 3000
*No hidden files.
* Could be due to including . and .. in the sum? (e.g. `ls -a` would have these)
* Tried creating new folder and copy/pasting all contents into it, result is the same.
* This issue appears in other folders on my system where there are more than 200 files.
* Not sure show the number of folders affects the count.
