A hidden file next to a normal one. The preview of the hidden one is noticeably smaller than the normal one.

SUMMARY
Using a new laptop I've quickly noticed that previews for some files are too small.
I've figured out the affected files are either hidden or symlinks.

STEPS TO REPRODUCE
1. Set display scale to e.g. 125%
2. Enable previews on files
3. View a hidden or linked file

OBSERVED RESULT
The preview is noticeably smaller than normal files.

EXPECTED RESULT
The preview is just as big as normal files.
